Books in the Matthew Riker series

Some skills you never lose. Killing is one of them.  Matthew Riker keeps to himself, doesn''t cause trouble, and never talks about his past.  But after a chance encounter with a woman and a small child on the run, Riker will have to make a choice: use his hard-won skills to protect two innocent victims, or stay in the safety of his quiet life. What follows is an adrenaline-soaked thrill ride that will take Riker on a cross-country chase, through the seedy underbelly of a New York criminal empire, and into the darkest places of the human heart.  Fans of John Wick, Jack Reacher, and Jason Bourne... get ready to meet Matthew Riker.
