The Finder by J.E. Lorin

At the age of sixteen, August Goodson developed a strange and mysterious power overnight: he can find people. Victims of murder, suicide, kidnapping, accidents, and rape; August can find them all, usually dead, but sometimes still alive. Nine years later finds August volunteering his services to the police. He’s still smarting from the loss of his long-time love Dante, who cheated on him with his best friend, and harbors a deep crush on the incredibly handsome, and oh-so-straight, Detective Luke Williams.

But there are bigger concerns on August’s mind: a serial killer is loose in the city, one whose victims are a little too much like him for comfort. When August finds a living victim who may be one of the serial killer’s, he’s drawn even deeper into the case. Will he make it out alive, or will he soon be the one in need of finding?
