Zero Day was first published in 2011 this is the introduction to Army CID investigator John Puller by David Baldacci. Zero Day is a fabulous read a gripping read and the sort of thriller people love to read. John Puller like his father and brother had served his country in the army. Unlike his father and brothers who had been officer he had been a grunt, and he also happened to be the best investigator in the army along with a chestful of medals. When an army colonel and his family are killed in West Virginia the Army CID is called in. The colonel had been in the Army Intelligence Division and Puller was informed there would be plenty of eyes on him. Already warned that this was an unusual case he would be a lone investigator with no back-up. As Puller arrives in Drake, West Virginia and the death count begins to rise and he seems to have far more questions than answers. Puller teams up with Samantha Cole who is the investigator for the local Sheriffs department. The further they dig they seem to upset someone at every turn and Puller can only rely on the one person he has known all his life. The only problem was that person was currently in federal prison for treason. This book is a roller coaster of emotions and suspense which keeps you on edge throughout the book. This is a really fantastic introduction to John Puller.

I always enjoy Baldacci and this was no exception - a good start to 2012!

Another fantastic book from Baldacci. I've not missed a book since picking up Absolute Power and have never failed to be gripped by the fantastic storylines. Great lead character and couldn't wait to get on the train every morning/evening to pick up the story. You will not be disappointed.

Zero Day by David Baldacci launches the John Puller series with a mystery thriller that leans heavily into investigation and atmosphere. Puller himself is an intriguing lead—clinical, particular, and unwaveringly methodical. Baldacci gives readers a character whose precision becomes the backbone of the story. The narrative unfolds piece by piece, offering vivid descriptions that anchor each scene. The pacing remains steady throughout, driven less by high-octane action and more by the meticulous accumulation of evidence. Each clue is examined with care, either interrogated or dismissed, creating a quiet but persistent tension that steadily pushes the reader toward the truth. The result is a procedural feel that rewards attention and patience. Zero Day delivers a grounded, detail-rich thriller that sets the tone for the John Puller series. If you enjoy mysteries that prioritise investigation over spectacle, with a protagonist who works through grit, logic, and discipline, this is a compelling start. It left me interested to see how Puller evolves and what challenges await him next.

oh, what to make of David Baldacci? A capable and entertaining author, much of his recent work has not been up to the standard set by his early books. My personal view is that this came about as he started producing books on a more regular basis, quantity over quality if you like. And now we have "Zero Hour" which is a very hard book to review... The good news is that this is the best book from the author in some while, a fast paced page turner about an US Military investigator looking into some deaths in a small town and realising there is a far bigger picture..... The bad news is that I am astonished at how this rips off Lee Child's Jack Reacher! A tall military cop who goes by his surname, adept with his fists or weapons, hightened obserrvaional an analytical skills, the setting of small town US and a lady sheriff to boot! It's almost like he went with a check list of a standard Reacher book! It's astonishing almost to the degree that it is funny. But it actually ain't bad and Reacher fans will probably enjoy this while thinking Mr Baldacci has a bit of a cheek. But the truth is, with the ripped off character and formula and Baldacci's ability, this works well and I have to say I enjoyed it.
