A former Navy SEAL, Cole Makani Hunter has returned home from a disastrous black ops mission without his best friend, his hearing, or the use of his right arm. So when his ex–commanding officer assigns him to an undercover mission at a rehab center for vets to discover who leaked sensitive military information to an enemy, he'd rather be anywhere but there. Almost immediately, Cole finds himself at odds with Annie Murray—a peace-loving ecotherapist whose dream is to open an animal sanctuary out of her home. While the two seemingly have nothing in common, their spirited arguments soon fuel a passion for each other.

But just as things begin to heat up between therapist and patient, dangerous complications arise. So does the past—and a shocking revelation that puts Cole and everything he now holds dear in the path of a murderous traitor.
