During a horrible blizzard an FBI agent in a moving SUV in New York City is killed by a nearly impossible sniper shot. As the storm wipes out evidence, agent-in-charge Brett Kehoe turns to the one man who might be able to help them: former FBI agent Lucas Page. Now a university professor and bestselling author, Page left the FBI years ago after a tragic event robbed him of a leg, an arm, an eye, and the will to continue. The victim was his former partner-- and the murder is only the first in a series of all-but-impossible sniper shots. Page must discover what hidden past connects the victims, before he loses all that is dear to him. -- adapted from jacket
