This was a disturbing book. It was well written and gripping. The "good" characters were sympathetic and engaging. I cared about them. The "bad" characters were despicable. I like that in a thriller.
The disturbing part was the story-line about a teen-aged Bible study group in an ultra-conservative Christian church engaging in exceedingly risky sexual behavior that leads to murder. The tension ratchets way up when the detective/dad investigating the bombing of a birth control clinic realizes that his own daughter could be a target of the bomber.
The novel explores the rigidity of the fundamentalist Christian culture and its disconnectedness from traditional morality and ethics -- and even traditional Christianity. That is disturbing enough. Add clinic bombings and murder, and the tension gets almost unbearable.
Plan on reading this one more or less in one sitting.
