The Alvarez Journal (Gabe Wager Series #1)

Once, Denver's small-time pushers sold nothing harder than dime bags of bad California grass. But in the last year, heroin has appeared on the streets of the Mile High City.
Detective Gabe Wager and his rookie partner spend their nights trailing dealers, making buys, and acquiring informants. After months picking up scraps, a stray piece of information is about to put Wager on to the biggest bust of his career. A letter from the Seattle DEA puts him on the hunt for nearly a thousand pounds of smuggled marijuana. The case could make Wager's career—if the smugglers don't kill him first.
