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

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. 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. She's been an agent with The Seymour Agency since 2016 and also gets what it takes from this angle. She’s looking for 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 and health initiatives from a fresh angle but also has that special something to stand out in a very crowded market. If you have a provocative idea, a great platform and/or credentials and/or other clear author hook, and a fabulous title and hook, I’d love to see it. Diversity is welcome!

Note that memoirs are particularly difficult to place unless you are “notable” or have a truly unique experience that aims to inspire. Many people go through extraordinary experiences and grow through them, but it takes something really special to grab an editor’s eye.

I suggest that all writers subscribe to Publishers Marketplace ( for at least a month and see recent deals posted in your category. This will give you a clear idea of what it takes to snag an editor’s attention, thus what agents are looking for as well. As much as we might love a certain project, we have to feel we can make you a good deal that’s worth the time and effort invested, including the editors who receive it.

I get a lot of great proposals that I have to pass on because of lack of platform, sadly. It’s really an essential part of a successful book sale and a book launch (which impacts the next book’s chances). If you have no platform or a small or unengaged one, please consider spending your query time building that up before sending your idea out into the world.

Please limit queries to self-help/non-fiction books. poetry, or children’s books, and please, no fiction. Even spiritual fiction.

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

Send your proposal 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, credentials, etc.), and sample chapters (in a Word RTF or PDF doc) through http://QueryMe.Online/TinaWainscottTSA (link to URL). This form makes it faster for me to hone in on the pertinent facts, and it includes information you can grab from your proposal (or that should be in there anyway). I’m looking forward to seeing your query and I will get to it as soon as I can!


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.

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 diverse and LGBTQ+ authors and wants to share more of these marginalized voices with the world.

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.

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.

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. ( 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 – diverse voices, 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.”


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.
