Back in 1945, the first portal opened--a tear in reality leading from our world into the mysterious Black Lands, a realm of perpetual night filled with strange and deadly entities.
Soon another portal appeared. Then another. Today, the government secures every portal they find, but with more and more opening, and no idea how to predict or prevent the next one's arrival, society is teetering on the brink of panic.
Felix Renn knows the Black Lands all too well. His career as a private investigator has dragged him closer to it than most, and has garnered him a reputation for dealing with supernatural threats. But people who interact with the Black Lands have a habit of turning up dead in horrible ways--if they turn up at all--so when the chance comes up to take on a simple missing person's case in the small town of Sycamore, Felix jumps at the opportunity.
Only, something else is happening in Sycamore. A serial killer is on the loose, and as the bodies continue to pile up, it becomes clear that the perpetrator may be something less--or something more--than human.
Felix may have thought he was done with the Black Lands, but he soon discovers a terrifying truth: the Black Lands isn't done with him.
