With my eyes closed and Alex's core friends all around me, it was like I'd become my big sister, or something just as good. And so who cared if they were calling it Alex's party? One thing I it would be remembered as mine. Alex has it all—brains, beauty, popularity, and a dangerously hot boyfriend. Her little sister Thea wants it all, and she's stepped up her game to get it. Even if it means spinning the truth to win the attention she deserves. Even if it means uncovering a shocking secret her older sister never wanted to share. Even if it means crying wolf. Told in the alternating voices of Alex and Thea, Adele Griffin's mesmerizing new novel is the story of a sibling rivalry on speed.
