Cammie Morgan has lost her father and her memory, but in the heart-pounding conclusion to the best-selling Gallagher Girls series, she finds her greatest mission yet. Cammie and her friends finally know why the terrorist organization called the Circle of Cavan has been hunting her. Now the spy girls and Zach must track down the Circle’s elite members to stop them before they implement a master plan that will change Cammie—and her country—forever.

I'm SO excited for this book! I've been following this series for years, and for this to be the last book is extremely bittersweet. I can't wait to return to the characters and the plot, but I don't want this series to end! Ally Carter is an amazing writer, so I know this book will be fantastic. Additionally, I LOVE this cover. It's so cute!
