Most girls spend their twenties worrying about student loans and bad dates. Sisters Samantha and Lizzie spent theirs learning how to pick a lock with a bobby pin and disappear into a crowd. They were supposed to be spies in training…emphasis on the training. It was all dead drops, brush passes, and counterintelligence.

Until the training wheels didn't just come off—they were shot off.

When the twins uncover a conspiracy involving a shadow organization hiding in plain sight, the CIA doesn't send them back to the classroom. Instead, they are thrust into the field with no backup, a suspicious amount of caffeine, and a mission to track a dangerously handsome operative who has "double agent" written all over his brooding jawline.

Trading their cardboard targets for enemies who have the irritating habit of shooting back, the sisters realize that spycraft is a lot less like the movies and a lot more like a game of high-stakes poker where everyone is cheating.

Can Samantha and Lizzie outmaneuver the shadows and unmask a mole? Or are they destined to become a cautionary tale in a classified file?
