As Darkness Falls - Number 1 in series

An abducted child. A ruthless killer. A race against time. Haunted by her failures, police detective Isabelle O'Connell is recalled to duty by detective Alec Goddard to investigate the abduction of yet another child from her old home town. With the killer playing a game of cat and mouse they have only days in which to find the girl alive, but they have very few clues, a whole town of suspects and a vast wilderness to search.
For Isabelle, this case is already personal; for Alec his best intentions to keep it purely professional soon dissolve. He starts to think of the missing child as if she were his own, and his anguish over Bella's safety moves beyond just his concern for a colleague. Their mutual attraction leaves them both vulnerable to their private nightmares - nightmares that the killer ruthlessly exploits .
