In this sequel to the romantic spy-thriller Two Lies and a Spy, Kari must race the clock on a mission to save her little brother.

Kari Andrews thought life was going to get easier. She was wrong. Following the events of Two Lies and a Spy, she and her brother, Charlie, are left to cope with the aftermath while also adapting to a new school—in another country. And then Charlie disappears.

With her brother’s life hanging in the balance, Kari, Evan, Rita, Kale, and some new friends from Generation Interpol (G.I.) are on a race around Europe at the bidding of a voice on a phone. The voice tells them that they need to jailbreak a thief—a flirtatious, hot thief—steal something from a high-security bio lab, and deliver the goods during what’s sure to be a double-cross exchange. Can they succeed before Charlie pays the ultimate price?
