Silent protector

"His life as a U.S. marshal was something Pastor Ian McNeal had left behind...until he's asked to care for little Charlie Troop. The boy witnessed a terrible crime and hasn't spoken since--except to his Auntie Liz, the one adult he trusts. Ian just wants to find the truth, something only Charlie can reveal. But Charlie isn't talking, and Liz is determined to protect Charlie against anyone who'd hurt, frighten or pressure him--including Ian. Yet with a killer dead set on making sure Charlie never speaks again, a protector like Ian is just what Liz and Charlie need."--P. [4] of cover.
