(Book)

"City of Windows introduces Lucas Page, a brilliant, reluctant investigator, matching wits with a skilled, invisible killer. To identify and hunt down this ruthless, seemingly unstoppable killer, Page must discover what hidden past connects the victims before he himself loses all that is dear to him"--,Provided by publisher.

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
