Double Helix Paperback - 2005

Since then, she has worked as a technical writer and editor for several computer software and Internet companies, while also writing fiction. She is a National Book Award finalist.

Of Nancy's suspense fiction, Sarah Weinman says, Chances are, many of you haven't heard of this author. That would be a shame, because she's simply one of the best crime novelists going right now. Period. These titles are where Nancy habitually breaks genre-separation rules and include The Rules of Survival (a National Book Award finalist), The Killer's Cousin (Edgar award winner), Locked Inside (Edgar award nominee), Black Mirror (which the Washington Post called an edge-of-your seat thriller), and Double Helix (named to multiple best-of-year book lists).

Nancy's unusual fantasy fiction was inspired by the ballad Scarborough Fair and includes the loose trilogy Impossible (a New York Times bestseller), Extraordinary (featuring a rare thing in fantasy fiction: a Jewish heroine), and her personal beloved, Unthinkable.

For fun, Nancy also writes and draws a graphic memoir in comics, using her Tumblr to self-publish an episode three times a week.

Her favorite book in all the world is Jane Eyre.

A graduate of Yale, Nancy lives near Boston, Massachusetts with her husband.
