Any book that can gain a blurb by Nathan Lowell is probably worth trying out. Here comes Sense Memory by Brion J. Humphrey:
Thrust into a search for his own sister’s killer, Benjamin Cady flees Colorado and the only world he understands to scour the streets of Los Angeles, plagued by headaches and memories of murder. He quickly discovers that L.A. is not unknown to him, and as his memories of his sister’s death become clearer, so does the possibility that Ben himself may be the murderer.
Lieutenant Jim Banquer has plenty of bodies, but every witness seems to be suffering from a mysterious form of amnesia. Investigating these deaths means he must piece together the scattered shards of a deadly power scheme that goes well beyond murder, and Ben is the key.
Sense Memory is a psychological thriller that weaves an intricate web of doubt and intrigue as it goes, leaving no thread unstrung. A sure page-burner, this story will stay with you long after the smoke clears.
