Typical thriller. Lots of twists and I didn't guess the killer, but I think that was only because there were too many characters. Would of liked to see more points of view and I got tired of all the speculating questions made by the main character. "Was the killer watching her? Did the killer work at the clinic? Was the killer a hitman? Was the killer involved in the victim's gambling debt? Does the killer like taking long walks along the beach at sunset?" Yea, those went overboard and some should have been left for the reader to speculate. That aside, the last hundred pages kept me up past my bedtime and I thought the use of the fertility clinic was an interesting aspect of the novel. Bring it to the beach.
