In many ways this book reminds me of one of those revenge-based action movies, you have a highly trained former military person out for revenge after his wife and unborn child are killed by the mob, but the author manages to elevate the story from this somewhat simplistic setup.
One thing that I am glad about is that the author didn't persist with the excessive listing of guns and ammo types that would have detracted from the actual characters and story while adding nothing to that story.
This book is mostly focused on a man named Dan Stone who used to be an army sniper and is now on a quest for vengeance against members of the mob that killed his wife and unborn child when they fire-bombed his restaurant. He basically declares war on an entire crime family, hurting them by destroying their operations prior to finally taking his revenge on the ones responsible.
Alongside Dan, there are a number of notable characters, some old school friends who get pulled into the fallout from his mission and of course a range of mobsters and law enforcement who are both trying to stop him, there is also one other person who might be able to offer him a purpose and to make use of his skills once he has finished his revenge mission.
With so many Italian-American characters featuring in this book it would have been very easy for the narrator to have given an over the top performance leading to caricatures rather than characters, but thankfully he refrained from this and went with more of a tone for these characters rather than a full-on accent and it worked well as they were suitably distinct without being a distraction.
Overall, this book was an interesting one that grew beyond the basic starting point into something more, it will be interesting to see if the main characters will remain interesting in subsequent books when the series will presumably move onto a less personal setting.
