Secrets can be deadly. In Paris, Savvy fell for Malcolm, the hot assassin, before her mom whisked her away. In Greece, Savvy meets up with him in the most awkward reunion ever...and almost gets him killed. Fail one. Her mom gives her one easy spy mission, one chance to prove she's ready, except she breaks the rules - for good reason, of course - and the mission implodes. Fail two. To prove her worth, Savvy lies to her mom and boyfriend and strikes a dangerous deal with Malcolm's family. All that seems trivial when an enemy threatens both families. Savvy has one last chance. She must convince their families to work together and infiltrate this unseen foe in her most dangerous mission yet. But nothing can prepare her for the sacrifice she'll have to make. One that might tear her and Malcolm apart forever.
