Get to Know Our Founder

Mary Sue Seymour

Mary Sue Seymour was listed by Publishers Marketplace as one of the top dealmakers in the country. She was formerly a member of the Author's Guild, the AAR, ACFW, WGA, and RWA** and was named as ACFW's Agent of the Year in 2015.

After graduating from the State University of New York, Mary Sue taught in a public school system for almost 15 years. While teaching, she completed graduate work at The State University of New York. At the same time, she wrote for national publications such as Junior Scholastic, The Artist's Magazine, The American Artist, and teaching magazines.

Mary Sue believed in the Bible verse in Romans 10:12 that states, "For there is no difference between Jew and Gentile - the same Lord is Lord of all and richly blesses all who call on him..."

Always in our hearts, we carry on her legacy and vision.


Nicole Resciniti

Nicole Resciniti has been listed by Publishers Marketplace as a top dealmaker in the country and named as ACFW's 2012 Agent of the Year. She loves discovering new talent and helping established authors to take their career to the next level.

Nicole is a member of AAR, ACFW, RWA, and Mensa. She holds degrees in biology, psychology, and behavioral neuroscience. Like Mary Sue, Nicole taught in the public school system and has worn many hats before heeding her calling to become a literary agent—for which she will forever be indebted to Mary Sue Seymour.

Do you have the next project to feed her book addiction? A smart, tight read she won’t be able to put down? A signature voice she’ll fight to represent?

A proponent for authentic, diverse voices in fiction, Nicole is actively seeking those stories that have to be told. #OwnVoices

HEA’s are a must for romance. Mainstream suspense, thrillers, mysteries, YA, and inspirational novels are welcome. A consummate science geek and card-carrying Mensa member, Nicole would love to find the next great science fiction/fantasy novel or action/adventure masterpiece. Currently on her wish list: high-concept middle grade, any kind of romance, and really fresh voices in YA.

"I have the best job in the world. I read for a living and make authors’ dreams come true."

Tina Wainscott

Tina Wainscott is the USA Today bestselling author of over 30 novels with romantic thrills and suspenseful chills. She’s been published with houses such as St. Martin’s Press, Harper Collins, Hachette, and Random House since 1995, so she understands the business from the author’s perspective. As an agent, she’s looking for self-help non-fiction that inspires people to reach for their best and overcome life’s challenges.

A Note from Tina:

“As I considered becoming an agent with this amazing agency, I knew what my area of interest would be as soon as Nicole mentioned ‘self-help’ as one of the categories on which they wanted to focus. Though I continue to write fiction, I am also invested in my own soul journey.

I love the feeling of reading a book that helps me transform, to see the world through a new perspective and its challenges in a new light. The idea of helping writers share their vision with others when it comes from their heart is thrilling!

I’m looking to work with a select few authors who have an idea that fits into self-help/ personal transformation/spiritual growth but also have that special something to stand out in a crowded market. If you have a provocative idea, a grasp on your platform, and a fabulous title and hook, I’d love to see it! Diversity is welcome!

Please limit queries to self-help/non-fiction books. No memoirs (unless it specifically aims to use your life/experience as a teaching tool or you are someone of note), poetry, or children’s books, and please, no fiction. Even spiritual fiction.”

Note: Please send religious/Christian queries to Julie Gwinn.

Send your query that includes your book’s blurb, what the book targets, clear marketing/platform info (e.g. your numbers as far as followers go, subscribers, professional connections, etc.), your proposal, and sample chapters (in a Word RTF or PDF doc) to http://QueryMe.Online/TinaWainscottTSA (link to URL).

Jennifer Wills

Jennifer has 5 years’ experience in some of the publishing industry’s leading literary agencies. She worked with publishers around the world as an assistant in Trident Media Group’s huge foreign rights department and with domestic publishers as an assistant at Writers House (where, incidentally, she began her career as an intern).

She joined the Seymour Agency in April 2016, where she has quickly moved up the ranks to Literary Agent. Jennifer has always loved helping fledgling authors become NYT bestsellers, and she’s ready to be a relentless champion for her own clients’ work.

Jennifer is particularly interested in a wide range of picture books and cookbooks, with a soft spot for author/illustrators of sweet and wacky picture books, and cookbooks with mouth-watering recipes of the health-conscious, budget-friendly, or celebrity chef variety.

For fiction, she’s also interested in middle grade and YA with a sci-fi/fantasy, horror/suspense, or contemporary bent, and upmarket women’s fiction with a sense of humor. 

On the non-fiction side, narrative non-fiction and memoir are also welcome. If your manuscript has a great hook, a distinct voice, and can make her laugh out loud or ugly cry (or even better, both), she’d love to see it. 


Lynnette Novak 

Prior to joining The Seymour Agency, Lynnette spent 17 years freelance editing. She worked with new writers, advanced writers, as well as the New York Times and the USA Today bestselling authors.

Lynnette earned a Bachelor of Education degree from the University of Manitoba, where she specialized in English and French. She excelled in Advanced Creative Writing in university and studied writing for children and teens through the Institute of Children’s Literature. She was a Pitch Wars mentor in 2015 and 2016. Both her mentees acquired an agent.

Although Lynnette was born and raised in Manitoba, Canada, she now lives in Minnesota with her husband, twin girls, and many pets. Her personal interests include reading, writing, exercising at the gym (okay, that’s a love/hate relationship), working on an assortment of crafts, all things having to do with animals (if she could own a farm, zoo, and animal shelter, she would), and enjoying time with family and friends.

She loves dark and suspenseful, mysterious twists, unique worlds, light and funny, a good love story, and lots of voice. Lynnette is always looking for own voices, diverse, and LGBTQ+ authors and wants to share more of these marginalized voices with the world.

Elizabeth "Lizzie" Poteet

Born in Nashville, Tennessee, Elizabeth “Lizzie” Poteet attended Colby College where she majored in English and Religious Studies. While studying at St. Andrews, she realized that though she enjoyed Shakespeare and the Dead Sea Scrolls, she preferred reading stories with a little more heat and heart.

Lizzie took her passion for romance and turned it into a position with RT Bookreviews as a romance reviewer. In 2011, she joined the editorial team at St. Martin's Press where she worked with romance, YA, non-fiction, and women’s fiction. Then in 2015, Lizzie became the e-book original coordinator for SMP Swerve, helping launch the digital-only romance imprint.

Lizzie is always looking for a good love story. She loves classic romance tropes, strong dialogue, sassy heroines, witty banter, and good old fashion romance. She’s actively seeking inspirational romance, cozy mystery, New Adult, YA, romantic suspense, genre romance (historical, contemporary, #ownvoices, and LGBTQ+), and loves anything with a happy ending.

Please no poetry, picture books, or literary fiction novels.


Michael L Joy

Michael L Joy is a graduate of the Stonecoast MFA Creative Writing program and a board member of the Florida Chapter of the Mystery Writers of America, where he is the co-chair of their annual mystery writing conference, SleuthFest. (SleuthFest.com). He is a professor of English, musician, and recovering programmer living in Southwest Florida.

Notes From Michael:


“I’m looking for character-driven commercial fiction in mystery/crime/suspense/thriller – including graphic novel script format. Stories that transcend genre and have the potential to attract a wider audience (aka Upmarket fiction). I’m excited to read new perspectives – #OwnVoices, race, gender, LGBTQ, or sub-culture - different POVs, obstacles and outcomes. Situational humor is good, but not required.

Cozies will be a tough sell unless the “community” is something extremely different. No talking or communicative animals. No Romance, but romantic elements are good if done well. Don't force it.

Before you submit… give your book a rest then edit for plot and polish for word choice, spelling and grammar. Let it rest again.

Submit the first 50 pages as a Word attachment. Include a synopsis. Don’t stress over the format, but make sure you include the inciting incident, obstacles to the main character’s goals, the climax, and the conclusion – yes, I need to know how the story ends.”


“I’m looking for art, music, pop culture or sub-culture topics, including positive mental and physical health for an artist. True crime. Business Self-Help: How to survive and keep positive while starting a business, running a business, or working a high-pressure job. I’d be excited to look at graphic novel formats for non-fiction also. No politics or religion.

The key to selling non-fiction is having an existing platform – first-hand expertise or experience – no arm-chair quarterbacking. If you’re going to write about winning the World Beard and Moustache Championship, you better be a competitor or a barber…or better yet, be both.

When sending your query please include a book blurb, what topic the book targets, clear marketing/platform information (e.g. social media followers, subscribers, professional connections, etc.), your proposal, a comparison in the market, sample index page, and three sample chapters.”


Joyce Sweeney

Joyce Sweeney has worn a lot of hats. She is the author of fourteen novels for young adults, and two chapbooks of poetry. She created and managed a local theater company in South Florida for ten years, mentoring local playwrights, producing and directing their plays. For the past twenty-five years, she has taught creative writing, both in person and online, and has mentored over sixty of her students to traditional publishing contracts. She has edited countless manuscripts and will be the quintessential ‘editorial agent’.

Most of all, she is a champion for writers and this new role is a great chance to take that to a higher level. 

What she’s looking for:

In Picture Books: Fiction or non-fiction. I am drawn to lyrical voices, fun syntax and offbeat concepts. I like unusual characters, and plots that make me cry or laugh out loud. Illustrator/authors welcome and rhyme (if you REALLY know how to do it) is fine. Diversity, please. Most of all, be unique. No graphic novels please. 

In Middle Grade: I am especially drawn to humor, fantasy and sci-fi, but a realistic novel that makes me cry will work too. Advocate of books for boys. Would love to see more LGBTQ as well.

Marketing Specialist

Leslie Nunez

Leslie Nunez is a recent grad from FIU’s Honor College, in which she was a member of Sigma Kappa Sorority and Office of Sustainability's intern. The beach is her go-to spot in Naples where she likes to listen to Charles Bukowski's poems and Alan Watt's hour-long videos on YouTube for relaxation. Leslie has been vegan for two whole years, which caused her close friends and family to lose the bet that she would not last as a vegan for more than a year. 


We believe that an organization such as Romance Writers of America must work for ALL of its constituents and do so honestly, positively, and proactively.

RWA proclaims a mission of inclusion and equality, yet that has not been evidenced in recent events. As such, we are withdrawing from the organization and will not participate in RWA Nationals or other events until such time as real and actionable changes are implemented.
