This one has the same kind of feeling one of my favorite series, the Rush McKenzie series has. The main character isn't really a PI and although he is quite skilled at what he does has a very Everyman kind of feel.
Greg Owen is the owner of several small businesses and has PI license he doesn't really use. He's asked by an old friend to prove a young man went to jail innocent of killing his highschool sweetheart. He ends up uncovering quite a number of old secrets while they try to warn him off the investigations. Besides that he's also got to deal with the fact his ex-wife and his daughter might be moving to a different city.
Greg is a guy that you might know and want to have a beer with. He's an ex-Marine but no macho tough guy. He's an okay investigator but no Sherlock Holmes. It's those facts and the easy, breezy style of the writing and not difficult plot and number of characters involved that make this one such a hoot to read.
I'll be sure to contact the author soon and tell him he's got a winner here. Author Evan Ronan is probably best known by his paranormal mystery series (featuring Eddie McCloskey), but I hope he'll be writing this series for a long time to come as well.
