Nicholas Sharp is a flawed hero, but you sure as hell want him on your side!
Turning his back on the military system that turned him into a murderer when he shot an innocent man, Sharp is grateful to have found refuge in a career as a successful musician. But while he is preparing to back well-known former rock star Robbie West on a USO tour of Iraq, a close friend and her daughter disappear.
In a deadly game of cat and mouse across three continents Sharp discovers there’s more at stake than his own life and those close to him. As relentless shadows from his past chase him down, he faces a brutal choice... kill or be killed.
If you enjoy Robert Ludlum’s Jason Bourne, Tom Clancy’s Jack Ryan, or Robert Crais' Elvis Cole, you need to meet Nicholas Sharp..

This was an interesting story with probably some truth in it. The characters were good and with an understanding of the parts played. I wish Nicholas Sharp and Jack Greatrex were a little stronger in their personalities, not so weak and undecided. The story line and the way the author put it together was good, only a small part was a little too wordy. Book well worth reading.

Marine sniper turns musician. A clever mix of two totally different worlds and a lot of soul searching.
Nicholas' past catches up with him when he has to save the lives of 2 people again when blackmailed into getting a chemical weapons sample out of Iraq.
With good insights into the concert world of rock bands as well as the military, this all comes together as a great thriller.

Piano Man

A fast-paced action story of a former marine who wants to forget that past life and live as the talented keyboardist he became. However, his past and present are ruthlessly exploited by a former officer with no moral compass who will stop at nothing to get what he wants. It's up to Nicholas to figure out how to prevent that terrible outcome.

Another operative in the Mitch Rapp and Scott Harvath echelon. He endures 3 serious concussions in the span of 24 hours, but like the Energizer bunny, he keeps going. Gets clocked in the groin but gets right up and chases. Ridiculous.
It’s an okay tale. A bit wordy. Felt longer than it was.
And it’s the start of a whole series but I don’t think I’ll pursue.

Shallow



Sorry but this did not do it for me, nor did it compare with the Reachers of the literary world.

I chose this book on amazon based on reviews making comparisons with these characters but I was left disappointed.

conventional or chemical weapons

Full of action and drama this is definitely worth the read. Completely involved in Nicholas and Jack’s loves I felt like I was fighting the good fight. Interested to see what happens next.

Okay reading

Not up to making Nick a bad ass which it seemed what the author was trying to do. Great effort but not quite there.

Did not finish. Yet another clueless author, too lazy to check details. There is no such thing as a Glock 19 revolver.

A former sharpshooter marine, Nicholas was now in a band, but still called on when help was needed.

Plenty of excitement in this book and the writing is very good.

An absolutely action packed thriller from go to whoa, with an endearing hero who is actually fallible, but still able to win through in the end. Highly recommended.

Good read. Well written. I particularly like the inner turmoil the main character struggles with in meteing out vigilante justice or turning a blind eye. I like the protagonist Nicholas Sharp. And, I look forward to reading more books by this author.

Mark, I really enjoyed the sniper-musician-reluctant warrior character and thought you brought to life his emotions nicely. I connected. Looking forward to the next chapter.
