by Kevin Guilfoile

Clones, cybeworlds with avitars chasing avitars; "Shadow World", crazy fundie serial killer, other serial killer, private eyes, lawyers,love, murder, mayhem, lies, etc. Talk about a page turner. Sort of drained me and wasn't too thrilled with one aspect of the ending, but it's a very good story.

Set in a not too distant future after human cloning is legalized, this debut thriller is a disquieting pseudo-scientific meditation on what happens when the teenage daughter of a leading fertility specialist is brutally murdered and her father uses his professional skills and a bit of DNA extracted from the death scene to create a copy of her killer. Unlucky, unlikely Justin Finn is the result of Dr. Davis Moore's faith that one day he’ll look into the eyes and soul of the man who raped and strangled Anna Kat and understand what drove him to do it. His plan destroys his marriage, compromises his professional ethics, and threatens his own life, but all these complications pale next to the repercussion his efforts to clone Anna Kat's murderer have on the young man whose future is as predestined as his origins. Despite the shades of Robin Cook that hover over this intricately woven and unsettling mystery, Guilfoile's pacing is solid, his characterizations well drawn, and his own future as a writer assured. --Jane Adams --This text refers to the Hardcover edition.
