Nasty (Nate Jepson) by Bret R. Wright

Retired Navy SEAL Nate "Nasty" Jepson meets a man on the run, carrying a bag full of beef sticks. When the guy gets killed and Nate manages to get away safe with the beef things get dangerous. When his landlady gets kidnapped things get even more personal.
While he struggles to stay alive and tries to get to the bottom of things Nate Jepson also finds some time for romance.
Nate is a pretty cool and competent PI, but not the kind of superman you might expect if you read that he used to be a Navy SEAL. Sure, he can take care of himself but he also gets scared a little and is not a flawless fighter.
The book's biggest strength is also the weakness. We really get in the head of Nate as he tells the story. It's a nice voice, and I really liked the guy. In some places all his asides started to slow down the pacing a bit, though.
If the writer tightens the writing just a tad this will be a great new series.
