Rebecca Serle is a full-time writer, which means she gets to wear pajamas to work. She went to the University of Southern California, then got her MFA from the New School in NYC. (She likes New York much more than LA, but don t tell anyone that.) Rebecca loves shiny hair, coffee, yoga, and pretending to be British. She, too, experienced heartbreak once. It worked out okay, though, because she turned the experience into this book. When You Were Mine is her first novel. Find out more at rebeccaserle.com.
