“Thrilling, grounded and impossible to put down. VIPER feels frighteningly real.”

“Bob Cox and the VIPER squad are some of the most memorable characters I’ve read in years.”

“Smart plots, believable tradecraft and a relentless pace. Highly recommended.”

“Once you start the VIPER series, you’ll want the next book ready to go.”

“Having read all of the viper books, this was a must read. Well I wasn’t disappointed. I read the book from cover to cover in one sitting (ok it was on a kindle, but you know what I mean).”

“Wasn't sure if I would like this book as it's not a normal choice crime and police BUT !!! Started reading and couldn't put it down great story line and characters are first class can't wait for next in series thanks again David Baker.”
