Combines classic teen themes... with a nifty spy hook.
This book is absolutely incredible.
I couldn't put it down.
I was so excited when I got this book I read it in 24 hours...11/10!
Tore through it in like 4 days, and really loved it. It's a nice guilty pleasure.
Best book in the world.
A must read follow up in Ally Carter's fantastic Gallagher Girls series.
