Tell Me Where They've Gone: A heart-pounding thriller with a shocking finale

FBI Agent Constantine Striker has lost everything-his job, his partner, his family-and he's no closer to solving the decade-long mystery of his sister's disappearance.

Alex Frost's career is in free fall. Branded a pariah after teaming up with Con, she's one mistake away from being fired.

The last thing they need is to work together again. But with Con closing in on his sister's fate and Alex searching for her missing friends after a trip to Mexico, they have no choice but to join forces.

To uncover the truth, they'll cross every line, break every law, and face an enemy more dangerous than they ever imagined.

In the explosive installment of the best-selling series, Con must decide if the truth will save him-or destroy him. And Alex will learn the hard way that sometimes the heroes are worse than the villains.
