The Marine, whose name was Peter, looked like he was made mostly of ax handles and shovelheads, bound together with thick rigger’s rope at the joints.

The enjoyable saga of Peter Ash, Nick Petrie’s itinerant, fresh-air hero, continues with Light It Up, a tale of legalized pot gone very wrong in Denver and its environs.

Peter, a combat-hardened Marine veteran, suffers from persistent claustrophobia caused by PTSD. In the last book he fell in love with a fiery woman named June, who has given him a year to readjust to indoor living. Then a friend, Henry Nygaard (Norwegian name; he’s from Minnesota) asks him to help him out with a problem in Denver. Henry’s daughter and her husband are running a business providing security for marijuana merchants – pot is legal in Colorado, but federal regulations force them to deal solely in cash, an irresistible magnet for crime. But the last cash delivery they were guarding disappeared entirely, along with Henry’s son-in-law. Peter shows up to help guard the next trip, and it goes very bad, very fast. Peter is left with a sense of obligation to find the criminals and bring them to justice, one way or another. But he has no idea the kind of power he’s up against.

The Peter Ash novels remind me a little of Stephen Hunter’s Bob Lee Swagger books, except that Peter is younger and his forte is hand-to-hand combat, not sharpshooting. But there is the same kind of honorable hero, slightly-over-the-top action, and slightly improbable endurance and triumph. Lots of fun. I’m not a fan of legalized pot, but I’m happy to report that the cannabis business doesn’t come out looking very admirable here.

Questions about the church and homosexuality show up, but no conclusions are drawn. All in all, great series, great book.
