Nowhere — Shane Christopher

Detective David Rodriguez and reporter Mari Kinsella met in the shadow of horror. Though their relationship survived the terrible things they experienced, they both still struggle to put those memories behind them.
 
But that's not to be. For a vicious serial killer is stalking the streets of New York. A killer who comes out of nowhere, kills in ways that echo the twisted crimes of murderers past -- and then seemingly vanishes. So far, nobody has come close to capturing him.
 
Once again, David and Mari must stop a madman. And to do so, they must follow a strange and deadly path, one that will lead them to the brink of the unimaginable -- and beyond.
