Sean McCarthy is a New York-based independent literary agent at Sean McCarthy Literary Agency, specializing in children's literature with a particular focus on picture books.
In brief
Sean McCarthy runs a boutique independent agency focused exclusively on children's and middle-grade literature — the sales record and stated interests align closely on picture books as the core category.
The agency's independent structure means Sean McCarthy likely maintains close, hands-on relationships with a smaller client roster than larger agencies — worth factoring in if you value direct access to your agent.
Query status was observed open as of April 2026 for picture books specifically — always verify the live submission form before sending, as boutique agencies can close without notice.
Writers submitting picture books should treat specificity as their edge: Sean McCarthy's focus on this category suggests deep familiarity with what works, so vague or trend-chasing pitches are unlikely to land.
As a solo agency, Sean McCarthy wears multiple hats — writers should expect an agent who is personally invested in every project they take on, but response timelines may reflect a lighter support infrastructure than larger shops.
Lately
Query status confirmed open for picture books, consistent with the agency's longstanding children's-literature focus.
What Sean is looking for
Picture books are Sean McCarthy's primary and confirmed active category. Given the boutique, children's-focused nature of the agency, this is where their attention and relationships are most concentrated. Writers should bring a distinct voice, a concept with genuine emotional or comedic resonance, and a story that understands the picture book form — not just a short story formatted for children.

How to query Sean
Confirm the form is still accepting submissions before drafting your query — boutique agencies run by a solo agent can shift status quickly.
Tailor your pitch specifically to the picture book form: demonstrate you understand pacing, white space, and the interplay between text and illustration.
Because Sean McCarthy runs an independent agency, personalization matters — if you can articulate why their list and approach is the right home for your book, do so specifically and briefly.
Keep your query letter tight and voice-forward; in picture books, how you write the query is itself a signal of your voice and craft.
Do not pad a thin concept with market trends — a genuinely original premise or a fresh emotional angle will stand out more than a comp-heavy pitch to a specialist who already knows the market deeply.
If you are an author-illustrator, make that clear upfront — it is a meaningful distinction in picture book submissions.
