"Seventeen-year-old Cordelia Koenig intended to breeze through her senior project. While her peers stressed, Cordelia planned to use the same trace-your-roots genealogy idea her older sister used years prior. And getting partnered with her longtime crush, Kodiak Jones, is icing on the cake. All she needs to do is mail in her DNA sample, write about her ancestry results, and get that easy A. But when Cordelia's GeneQuest results reveal that her father is not the person she thought he was, but a stranger who lives thousands of miles away, her entire world shatters. Now she isn't sure of anything--not the mother who lied, the man she calls Dad, or the girl staring back at her in the mirror. If your life began with a lie, how can you ever be sure of what's true?-- Publisher's description."-- Provided by publisher.
