In brief
The submission form was directly observed open as of May 7, 2026 — overriding older directory data that listed Jennifer Newens as closed.
Client Tenisha Bernal's board book series points to a concrete track record placing concept-driven children's books; writers in that space have real evidence this agent can execute.
Client Deb Vanasse spans both literary fiction and narrative nonfiction, suggesting Jennifer Newens is comfortable with authors who work across categories rather than staying in one lane.
The roster skews toward food, nature, and domestic/family themes — writers whose work orbits those worlds are pitching into a demonstrably receptive taste.
Despite a broad genre label of 'diverse fiction,' the actual sales record is small and heavily weighted toward children's and nonfiction; query in those areas with highest confidence.
Lately
Jennifer Newens's active client list includes Tenisha Bernal, whose board book series covering kitchen and garden vocabulary for toddlers has resulted in multiple published titles — signaling an ongoing, productive relationship in the children's concept book space.
What Jennifer is looking for
Jennifer Newens has confirmed sales in the children's board book space, particularly concept-driven titles built around everyday worlds (kitchens, gardens, first words). Picture books and early concept books appear to be a genuine specialty, not just a stated interest. Authors who are also illustrators should note this distinction — it's worth clarifying that status in a query.
The roster includes narrative nonfiction with dramatic, adventure-driven storytelling — think historical obsession, natural environments, and high-stakes human endeavor. Writing that blends research with page-turning momentum fits the pattern of what has already sold.
Fiction with complex mother-daughter dynamics, characters making desperate pivotal choices, and settings that carry thematic weight (nature, place, identity) aligns with what the client roster signals. This is a selective taste — not genre or plot-heavy fiction, but emotionally grounded literary work.
Cookbooks and food-related nonfiction appear consistently across both stated interests and the client roster's thematic DNA. Practical, voice-driven food books likely land better than purely aspirational lifestyle titles.
Self-help is listed among Jennifer Newens's represented categories. The sales record does not yet illuminate a particular niche within self-help, so writers in this space should make the book's platform and audience as concrete as possible in their pitch.
Jennifer Newens lists diverse fiction as a category of interest. Given the limited confirmed sales in adult fiction more broadly, treat this as a developing priority rather than an established strength — query with strong comps and a clear sense of the book's emotional core.

How to query Jennifer
The submission form was live and open as of May 7, 2026 — confirm this before submitting, as status can change without notice.
Lead with category clarity: Jennifer Newens represents a deliberately focused list (children's, nonfiction, cookbooks, select fiction), so name your category and word count in the first sentence.
Children's book writers should specify whether they are an author-illustrator or author only — this distinction matters for picture books and board books and will likely be a factor in how the submission is evaluated.
If pitching nonfiction, open with the book's core argument and your platform or credentials; the roster suggests a preference for writers who bring both subject mastery and an audience.
Cookbook pitches benefit from a clear sense of the book's angle or community — food books tied to a specific culinary tradition, lifestyle, or underrepresented perspective fit the thematic texture of the existing client work.
For fiction, anchor the query in emotional stakes and character transformation rather than plot summary; the literary fiction on the roster rewards interiority and place over event-driven storytelling.
Martin Literary Management is Seattle-based — regional Pacific Northwest writers and nature/landscape-adjacent projects may find a particularly warm reception given the roster's environmental and place-driven themes.
Keep the query letter tight and professional; there is no public record of Jennifer Newens requesting unusual materials (e.g. full manuscript upfront) so follow standard industry practice unless the form specifies otherwise.
