The Man Who Walked in Darkness (Miles Franco #2) by Chris Strange

Miles is back for another round of hard-boiled urban fantasy action in the two-fisted sequel to The Man Who Crossed Worlds. Freelance Tunneler Miles Franco is having a bad time of it. He's facing a trial that could see him spend the rest of his days in prison. Hallucinations of dead men haunt him day and night. And to top it all off, one of his bandmates has been poisoned by a toxin from another world. Miles doesn't take kindly to people killing his friends. Now he'll have to walk the darkest road he's ever been down. With corrupt corporations on one side and fanatical interdimensional gangsters on the other, he doesn't hold out any hope he'll come out of this alive. But he has a promise to keep. And Miles will burn every last world to the ground if it gets him answers.
