Oh man, I LOVED this. It's so different from a lot of YA spy novels out there. It's a bit darker. You get more into the protagonists head. Lex's life is so complicated and it's really fun joining her as she navigates through it. Tons of twists and turns in this one and good Lord, the ending killed me. I loved it.
Also, loved her romantic relationship with Grant. He was so my kind of guy!
