Another reviewer was completely accurate in describing the immature sex scenes which the author seemed to feel necessary throughout the book. I felt he portrayed police and investigators as sex-starved, mindless twits who were too easily distracted from their case. There was no reason to care about any character, which made the ludicrous, slap-it-together ending less of disappointment. Pop-lit with some relationships what you're looking for? This is it. But for someone seeking a plot that actually keeps you guessing and surprises you with a satisfying ending, keep looking. And please let me know when you find it.
