Talk about an appropriate title! This book was a crazy ride and I loved every minute of it! I had a theory at where things were headed but nope, plot twist proved me wrong. My second theory was also way off base. I don't know how he does it, but Brian O'Sullivan keeps turning out books that blow my mind.

Absolutely loved reading what was truly a clusterf*ck story! Perfect title. Loved the short chapters, this book kept you interested all the way through! Definitely one of my top faves now.
