The Vicious Cycle: A Ronan Marino Mystery (Paperback) (ISBN-13: 9781505811209)

The best private eye money can't buy is back in an all-new mystery.

For the first time in years, former Air Force OSI Special Agent Ronan Marino is enjoying a rare stretch of peace. His relationship with a brilliant doctor is turning serious, his family has grudgingly accepted his unconventional post-military career as a private detective, and he's even considering going into business-opening a bar and grill with an old friend.

But that calm doesn't last.

When a violent outlaw motorcycle club rolls into Lowell and challenges the local Colombian cartel for control of the drug trade, tensions threaten to erupt into a full-blown gang war. Ronan swears to stay out of it and let the police handle the chaos.

That promise shatters when someone close to him is found executed and his girlfriend falls into a dangerous spiral, hooked on the very drugs the bikers are pushing. With the people he cares about at risk, Ronan charges headlong into the fight, once again diving into the darkest corners of the city-where even angels fear to tread.
