I rally thought this book had a great premise....healthcare conglomerations killing off the patients who used "more than their share" of resources. Okay....that wasn't it! So much of the book was just plain implausbible. I do not believe gang members talk that way. I don't see any real reason for the gang members to be in the story to start with! I think the coincidence of Jack and Therese meeting in the bar is unbelievable. I knew who the killer was about halfway into the book.I started reading Robin Cook in junior high...Coma and the rest. I think his last several books have been just churning them out, as simplistically as possible.
