As he drifts from place to place, he takes on labor that utilizes his muscle and expertise. But challenges dog Ash, and trouble seems to follow him in his wanderings. In his newest installment, LIGHT IT UP (G.P. Putnam’s Sons), he leaves a simple life rebuilding hiking trails in Oregon to help his good friend Henry Nygaard, whose daughter runs a Denver security company that protects cash-rich cannabis entrepreneurs from modern-day highwaymen. Henry’s son-in-law and the company’s operations manager were carrying a large sum of client money when their vehicle vanished without a trace, leaving Henry’s daughter and her company vulnerable. When Peter is riding shotgun on another cash run, the cargo he’s guarding comes under attack and he narrowly escapes with his life. As the assaults escalate, Peter has to wonder: for criminals this sophisticated, is it really just about the cash?
