Things aren't easy for Evan Tolliver. He's been spending so much time in the command center that he's failing most of his classes. Amy won't return his texts. And to make things worse, things are getting tense in Attleboro. There's a mole in the organization, and as the only non-Cahill in the inner circle, Evan is an obvious suspect. Is Evan being treated unfairly? Or is there a reason Ian doesn't entirely trust him? (That is, beyond his fashion sense.) Could Amy's adorkable boyfriend really be the Vesper Mole?
