Our esteemed guest reviewer, Shirley Ayers, sent in this review of David David Baldacci's 

Zero Day (#1), which was published in 2011. 

"Chief Warrant Officer John Puller is both a combat veteran and a military investigator in the U.S. Army’s Criminal Investigative Division.

"When Army Colonel Reynolds and his entire family are lined up and brutally killed in their home in Drake, West Virginia, Puller is sent to investigate.  He teams up with Drake Police Sgt. Samantha Cole to solve the murders.

"Puller is always prepared with all the right equipment from either his car’s trunk or his rucksack.  Sometimes he and he equipment seem to be testing our powers of imagination, but this is fiction, folks, so anything is possible."

Thank you, Shirley!
