Julie Dinneen is a D4EO Literary Agency agent whose core appetite is upmarket and commercial women's fiction — books with gorgeous prose that a book club will still be talking about three rounds of wine later — plus romance with sweep and scope, and select high-concept YA, thriller, and horror.
In brief
Dinneen's wishlist centers on the women's fiction / upmarket fiction / romance triangle — these categories appear with the most specificity and the most named touchstones, suggesting they are the truest sweet spot.
Romance is genuinely welcome here, and not just in its safest form: Dinneen explicitly names epic, genre-bending romance (think multi-book sagas with historical sweep) as a personal weakness, which is a meaningful signal for ambitious romance writers.
Thriller, horror, and YA are listed but come with explicit 'selective' language — Dinneen wants only standout projects in those categories, so writers in those lanes should approach only with exceptional material.
The submission address appears to be a dedicated query inbox (jdinneen.submissions@gmail.com) separate from the agency address, which is worth confirming against the live form before submitting.
Query status is unverified — the most important step before submitting is confirming whether Dinneen is currently open through the agency's live submission page.
Lately
Dinneen's wishlist emphasizes an immediate, unshakeable hook — the first page needs to earn continued reading, whether through the quality of the prose, the distinctiveness of the voice, or some harder-to-name magnetism. This 'first page test' standard is stated explicitly as a universal requirement across all categories.
What Julie is looking for
Dinneen wants literary fiction that hasn't sacrificed commercial readability — the kind of book with prose you underline and a story you can't abandon. Strong, distinct voice and wide audience appeal are both required, not traded off against each other.
Book-club fiction is a clear priority: multigenerational stories, emotionally rich domestic narratives, and sweeping historical fiction that generates discussion. Dinneen is drawn to stories that feel urgent and lived-in, the kind a reading group will argue over for months.
Well-executed romance across subgenres is welcome, with a special pull toward epic, genre-bending love stories that span time periods or cultures. Paranormal romance is not off the table, but the world must feel believable and the concept must be genuinely fresh — this is an 'only if it's exceptional' subgenre, not an automatic yes. Contemporary romance is listed among Dinneen's favorite subgenres.
Dinneen is looking for the spiritual successor to classic chick lit — sharp, funny, emotionally honest fiction that speaks to a millennial sensibility. The emphasis is on fun that's perfectly crafted, not just breezy: the writing still needs to sing, and the protagonist needs to feel like someone readers want to follow obsessively.
Dinneen will consider contemporary YA (listed as a favorite subgenre) and high-concept YA with genuine blockbuster ambition. This is a selective lane — the concept and execution both need to be extraordinary. Writers should not assume a solid YA manuscript is enough; Dinneen is looking for the rare project, not the well-crafted one.
Female-centric thrillers and psychological suspense (including romantic suspense, listed as a favorite subgenre) are on Dinneen's radar, but with the same selectivity applied to YA: only stories with relentless narrative grip will clear the bar. The psychological complexity must be genuine, not just a marketing label.
Dinneen reads less horror but will consider projects where the psychological complexity is the point — not pure shock or gore, but horror rooted in character and dread. Only standout work in this category is likely to receive an offer of representation.
Memoir appears in Dinneen's non-fiction list. No specific guidance is available on what type of memoir is preferred; writers should confirm this is currently active before submitting.
Humor is listed across both fiction and non-fiction. Given Dinneen's appetite for fun, perfectly-executed commercial fiction, humor that serves a strong narrative is likely the best fit rather than pure humor collections.

How to query Julie
Send queries to the dedicated submission inbox (jdinneen.submissions@gmail.com) — this appears to be a separate address from the general agency contact; confirm this is still active before submitting.
Paste your query letter AND the first ten pages directly in the body of the email — no attachments for the initial query.
Lead with the hook: Dinneen's own stated standard is whether the opening grabs them immediately, so your query letter must mirror that energy and your first pages must deliver on it.
For romance, name your subgenre clearly and, if your work has epic or genre-bending scope, say so — Dinneen has a stated affinity for ambitious, sweeping romance and won't be put off by scale.
For thriller, horror, or YA, frame the project around what makes it genuinely exceptional — Dinneen is explicitly selective in these categories, so a query that sounds competent rather than extraordinary is unlikely to succeed.
If querying upmarket or women's fiction, a comp that places your book in conversation with book-club-friendly titles signals you understand the intended readership.
Response time can range from under an hour to a month — do not follow up prematurely, but a query that has received no response after four weeks is likely a pass.
Always verify query status and submission guidelines on the D4EO Literary Agency website before sending — guidelines can change between the time this profile was compiled and when you submit.
