Query: Excellent Book

Great read and wonderful story. I highly reccomend. I bought the book just because I like Koontz and love Golden Retrievers (which was on the cover). I was super happy when it turned out to be my favorite book by Koontz so far. I like how he draws you in with different characters and there lives by chapter. It's even better when those lives connect to each other. I always find that I want to focus on one or two people and there lives. Then when they connect I get super excited. This book was no different and I loved it. Plus what can be better then a thrilling story revolving around a dog : )
