The Man Who Crossed Worlds (Miles Franco #1) by Chris Strange

All freelance Tunneler Miles Franco wants is a bit of freedom and a couple of bucks to rub together. So when the cops haul him downtown for smuggling people between worlds, he’ll take any chance he can get to stay out of the pen. And funnily enough, the cops have just the job for him. A mysterious interdimensional drug lord is staking his claim on Miles’ city, and the cops need Miles’ expertise to cut off the drug lord’s supply before it starts the biggest gang war in the city’s history. But snooping around in gang business is a dangerous job in a town where everyone’s on the take and the gangsters play for keeps. And there are a lot of ways a nosy Tunneler can disappear. Raw, insane, and hard-boiled as hell, The Man Who Crossed Worlds is a violent fever-dream for those who like their urban fantasy to kick them in the teeth.
