When his homecoming is rocked by an explosion, former FBI agent Rick Cloud puts R&R on hold. His undercover instincts warn him he's the target; his Navajo gifts tell him the reason is well hidden...deep in the walls of Copper Canyon. And only local beauty Kim Nelson can lead him to it.

Concealed in the canyon is a message from his foster father that only Rick can decipher. Trapped in the line of fire, the lawman loner knows only one thing: he must protect Kim from danger...and himself from giving in to desire.
