Approximately one billion debut novels are published every year, but it's rare to find a debut novel as assured as Doug Dorst's Alive in Necropolis. There's sex, violence, crime, oodles of head injuries, a half-assed practitioner of Zen, and a few supernatural happenings. Dorst is a young writer with a bright future ahead of him, making this a rare opportunity to catch a memorable writer early on the road to greatness.
