Liza DeBlock is a commercially-minded literary agent at Greenstone Literary whose list spans genre-bending fiction—thrillers, historical fiction, fantasy, and speculative romance—alongside food writing and women's-focused nonfiction, with a marked instinct for work that crosses boundaries and surprises.
In brief
Her confirmed client roster already reveals her taste clearly: she has sold food writing with awards pedigree (Fortnum & Mason Debut Food Writing winner Sally Abé), genre-crossing thriller writers, HWA-nominated historical fiction, and speculative literary fiction — signalling she can place ambitious, hard-to-categorise work at the commercial end of the market.
Her background at a literary scouting firm — where she worked on rights for Sunday Times and New York Times bestsellers including Richard Osman and Abigail Dean — means she thinks internationally from day one; writers with strong foreign-rights potential may find a genuine advocate here.
She is vocally drawn to fiction that defies easy shelving: thrillers with speculative DNA, historical novels haunted or fantastical, love stories with time-travel or magic, and fantasy rooted in world folklore. Books that sit comfortably inside one genre are less likely to excite her than books that productively break the genre's rules.
Her nonfiction wishlist is narrow but specific — food memoir, cookbooks, and women's health (maternal, sports, mental) — and she explicitly values credentialed experts and platform-holding creators over generalists.
She was named a Bookseller Rising Star in 2022 and works with Black Girl Writers, suggesting genuine investment in broadening whose voices reach mainstream publishing.
Lately
Her agency page describes a career arc that moved from literary scouting — learning the international rights market — to agenting at a boutique agency where she sold rights for multiple major bestsellers, before launching her own curated list at Greenstone. The page emphasises her international selling instincts from the start.
What Liza is looking for
She gravitates toward thrillers that bring something structurally or atmospherically unexpected: an offbeat or unusual setting, a speculative element woven through the plot, or a protagonist whose profession is genuinely distinctive and central to the story. Standard domestic suspense without a differentiating hook is less likely to land. Her confirmed client roster includes multiple thriller writers, confirming this is where she actively sells.
She wants historical fiction that asks readers to revisit, challenge, or fundamentally reframe a real historical figure — not simply dramatise well-trodden ground. A strong secondary hook elevates the pitch dramatically: gothic atmosphere, magical realism, fantastical elements, or an outright haunting woven into the narrative fabric. Her time working in archives and studying in Scotland means Scottish or archival settings carry genuine personal resonance and could be a real differentiator.
She is actively hunting an elegant, sweeping love story with a speculative dimension — time travel, magic, grounded fantasy, or a singular setting that makes the romance feel genuinely fresh. She also welcomes romcoms, provided the writing is sharp and witty, the heat level is real, and classic slow-burn or enemies-to-lovers dynamics are executed with intelligence rather than formula.
Her appetite for fantasy centres on original world-building: a magic system that feels genuinely invented rather than derivative, unusual creatures, and romantic threads running through the narrative. She has a particular pull toward folklore-inspired fantasy drawn from traditions beyond the Anglo-European canon — global mythology and underrepresented cultural sources are a specific priority.
She describes herself as hunting the intersection of commercial, book club, and literary — work that reads accessibly but has thematic or stylistic ambition. This is the broad tent her genre-specific categories sit under; a novel that doesn't fit neatly into thriller, fantasy, or historical fiction but has strong writing, a fresh hook, and wide-audience appeal is still worth pitching.
Food is a genuine personal passion — she bakes herself — and her client list already includes an award-winning debut food writer and a cookbook author. She is open to both narrative food memoir and practical cookbooks, prioritising strong authorial voice and either demonstrable expertise or a compelling platform. This is one of the few nonfiction categories where her sales record is already confirmed.
She specifically wants nonfiction addressing women's health through the lenses of maternal health, sports and physical performance, or mental health. The ideal submission comes from a credentialed expert or someone with direct lived-experience authority, not a generalist take. Work that challenges prevailing or accepted thinking on these subjects is particularly welcome.
Her nonfiction reading list skews toward revisionist history and cultural criticism that centres women — figures who have been overlooked, misrepresented, or actively written out. A confident, expert voice and a reframing argument are the key requirements; she is drawn to books that dismantle a received narrative as much as they build a new one.

How to query Liza
Use the exact subject-line format she specifies: TITLE – Author Name – Genre. Deviating from this format is an easy reason to be overlooked.
For fiction, the covering letter should be in the email body and must include: genre, word count, an elevator pitch, comparison titles, a book blurb, a brief author bio, and any writing credentials. Attach a 1–2 page synopsis and the first 50 pages OR first three chapters — whichever is longer.
For nonfiction, the covering letter should include: genre, intended completed manuscript word count, projected completion date, a full pitch, and a clear statement of your credentials or expertise in the subject area. Attach your full book proposal and any sample material not already contained in it.
Do not query with an unfinished manuscript in any category — she explicitly does not want partial work.
Lead with what makes your book genre-defying or categorically surprising: her wishlist consistently rewards projects that blend or transcend a single genre. If your thriller has a speculative edge, your historical novel has a Gothic flavour, or your romance features magic, say so immediately and confidently.
Comparison titles should be specific and recent. Her own reading list — which includes The Ministry of Time, Fourth Wing, Babel, and Notes on an Execution — gives you strong signals about the tonal register she responds to; matching your comps to that sensibility is more persuasive than generic bestseller comparisons.
For fantasy, foregrounding a unique magic system and any folklore or mythological influences from outside Western European traditions will speak directly to her stated priorities.
For nonfiction, lead with your credentials or platform before the concept — she explicitly prioritises experts and creators with a distinct base of authority.
She works with Black Girl Writers and has a track record of selling internationally; writers from underrepresented backgrounds and those whose work has clear international rights appeal are actively welcomed.
