Query: confusing and implausible

This book was fun to read and well written. Lehane creates colorful characters, and makes them seem extremely lifelike. But this book is excessively violent, and the ultimate "reveal" is simply not believable. Nor are many of the plot twists along the way. Reading this book is like guzzling a 6 pack of diet soda -- tastes good going down, but leaves you feeling empty and slightly dirty inside.
