Maggie Sadler is a Howland Literary agent with a graduate background in comparative literature and folklore who hunts for risk-taking adult literary and upmarket fiction, atmospheric magical realism, and expert-driven narrative nonfiction — with a particular soft spot for folklore retellings, unreliable narrators, and liminal settings that feel untethered from ordinary time.
In brief
Sadler is currently closed to queries while on medical leave recovering from major surgery; her own form advises checking back in June 2026 for a status update.
Her academic formation — a joint honors MA in Comparative Literature and English from St Andrews, plus a second MA in Literary Studies from Memorial University of Newfoundland — shapes a taste that skews scholarly, folkloric, and formally inventive; she is not a commercial genre agent.
Her 'white whales' list is unusually specific and revealing: she names touchstone authors (Karen Russell, Kirsty Logan, Susanna Clarke) and specific TV properties (Black Sails) as mood references, signaling she responds to atmosphere, moral complexity, and unhinged formal ambition over clean marketability.
She draws a hard line against work for young adults and younger — she is exclusively focused on adult readership — and against epic fantasy, all science fiction, and 20th-century war narratives, making her a poor fit for many genre writers despite surface-level crossover terms like 'speculative' or 'gothic.'
Her dual role as a literary agent and working editor/writing coach suggests she is a developmental partner, not merely a deal-maker; writers with manuscripts that need a thoughtful, hands-on collaborator may find a strong advocate here.
Lately
Sadler posted a notice confirming she is on medical leave following major surgery and has closed her query inbox for the duration. She asked writers to return in June 2026 to check whether submissions have reopened.
What Maggie is looking for
This is Sadler's core focus. She wants accessible literary fiction that still moves — propulsive hooks, skillfully engineered tension, and prose that is stylish without being precious. Themes should feel timeless yet reframed. She is particularly drawn to work that dismantles or subverts the conventions of its own genre or structure. Liminal, geographically unusual settings (islands, rural pockets, places that seem to float outside ordinary time) are a genuine passion point, as are morally complex, unreliable, or 'unhinged' narrators. She actively welcomes debut voices, especially from Indigenous and First Nations, BIPOC, and queer writers.
High-concept hooks married to nuanced socio-cultural commentary. Characters must feel unmistakably human and emotionally specific. She is looking for the kind of upmarket novel that earns its commercial appeal through insight and emotional honesty rather than formula. Genre-blended projects described as 'X meets Y with strains of Z' genuinely excite her — she treats cross-genre ambition as a feature, not a liability.
Listed explicitly as a 'white whale,' meaning she is actively hunting for this. She does not want reverent or decorative retellings — she wants work that sours, warps, or consumes the conventions of its source material. Non-Western tales and non-Western settings are of particular interest, likely reflecting the gaps she sees most often in her submission pile. Her St Andrews and MUL academic background in folklore studies gives her sharp editorial instincts in this space.
She specifies a restrained, grounded approach: the fantastical should feel like a possibility flickering at the edge of perception rather than a confirmed supernatural fact. Lush, atmospheric prose that keeps the reader slightly off-balance. She cites Karen Russell, Julia Fine, Kirsty Logan, and Hayao Miyazaki as reference points for tone and sensibility — the common thread is lyrical strangeness rooted in the everyday.
She wants intelligent, carefully constructed Gothic — simmering with dread and uncanniness, painstakingly crafted rather than atmospheric by default. One meaningful gate: she explicitly does not want Gothic set in the American Deep South. All other settings are welcome, and non-Western or under-explored Gothic locales would likely appeal to her cross-cultural instincts.
She is drawn to historical fiction that centers perspectives and geographies that are routinely overlooked or suppressed — not the standard Eurocentric narrative. She also has a specific interest in a well-researched, character-driven take on the Golden Age of Piracy, noting that the hook and character complexity matter more than historical fidelity alone. She cites John Silver from the series Black Sails as a tonal reference for the kind of morally textured protagonism she wants. Note: she explicitly does not want fiction set during WWI, WWII, or the Vietnam War.
She is actively seeking translated adult fiction across all the fiction categories she represents. This is a stated priority, not a passive openness — writers and translators working with non-Anglophone literary or upmarket fiction should take note.
She wants nonfiction that feels urgent and revelatory — stories not yet told, anchored by genuine expertise and authorial passion. Her topical interests are specific: travel, health and wellness, ecology and nature, and cultural criticism. She reads nonfiction as a lifelong student; the work should leave her with meaningful new knowledge or a transformed perspective. Projects that blend these topic areas or bring an unexpected angle are welcomed.

How to query Maggie
Do not query until the form reopens — it was confirmed closed on 2026-04-13 while Sadler is on medical leave. She has asked writers to check back in June 2026 for a status update. Querying now will receive no response.
Do not query by email under any circumstances unless you have had prior direct contact with her. She is explicit and emphatic: email queries are not accepted.
Do not send multiple queries for the same project. She reviews every submission personally and asks for patience.
Lead your query letter with what makes your book formally or conceptually risky. Sadler responds to manuscripts that break or interrogate conventions — if your pitch sounds safe, revise it to foreground the subversive or unusual element.
If your project blends genres or defies easy categorization, lean into that. A 'X meets Y with strains of Z' framing is specifically something she names as appealing — treat it as a feature of your pitch, not a liability.
For folklore or fairy tale retellings, specify the source tradition and make clear how your book warps or weaponizes it rather than decorates it. Non-Western source material is of particular interest to her.
For narrative nonfiction, establish your expertise and the urgency of your angle upfront. She reads nonfiction to learn — show her what she will walk away knowing that she didn't before.
If you are a debut writer from an Indigenous, First Nations, BIPOC, or queer background, her wishlist directly names these voices as priorities she is actively seeking.
Avoid querying WWI, WWII, Vietnam War fiction, Deep South Gothic, epic fantasy, any science fiction, or any work for younger than adult audiences — these are firm passes, not soft preferences.
