I'm a passionate fiction editor who loves helping writers tell compelling and moving stories. Having worked at Penguin Random House, Macmillan, and a top-tier literary agency, I have firsthand knowledge of what the country’s top agents and publishers are looking for—and how to get your manuscript noticed.

Between working in traditional houses and freelancing, I’ve evaluated and edited hundreds of novels, giving me a strong sense of what qualities help get a manuscript represented, acquired, and sold to readers. My experience spans line editing through multiple rounds of revision, high-level developmental editing, crafting thoughtful and constructive editorial letters, revising query letters, and evaluating manuscript submissions.

I'd love to help you refine your novel to flex its strengths or help craft a query letter that catches attention. I specialize in thriller/suspense, historical fiction, and contemporary women’s fiction. In short, anything that can be devoured in one sitting and spurs conversation!

Publishing can be an intimidating process to pursue on your own. Feel free to reach out with any questions you have about how we might work together. I’m here to help!
