Floating Staircase is a very creepy ghost story. It's about a writer named Travis Glasgow who moves into a house in a small town called Westlake. He starts to notice strange things happening in his house, and soon discovers that the previous owner's drowned in the lake behind his house. There is a mystery though as to weather it was an accident or a murder. Travis feels compelled to investigate the case because of his unresolved guilt from his role in the drowning death of his younger brother. From there, he begins a slow decent into madness and obsession.
This was one of the best horror novels I've read this year. If you're a fan of horror, or just good stories, you should read this book.
