Gilly Segal grew up in Tampa, Florida. She graduated from the Hebrew University and Emory School of Law. Gilly is the author of two young adult novels Kimberly Jones: I'm Not Dying With You Tonight and Why We Fly and the short story World of Wonder in the Game On anthology, all co-authored with Kimberly Jones. Her novels have been on the New York Times Bestseller list, nominated for an NAACP Image Award, book club selections for major retailers and received starred reviews. She has been nominated at a Georgia Author of the Year and her books have been nominated as Books All Young Georgians should read.

In addition to writing, Gilly serves as the Chief Legal Officer of an advertising agency. She lives in Decatur, Georgia with her three kids and her poorly-behaved Bernedoodle, and when she's not lawyering or reading or writing, she can probably be found watching a hockey game.
