Weird things happen in a building in L.A. and tenants band together to try to figure out what is going on. I thought based on the blurbs/cover that this was a mystery, but it is more of a science fiction story, so not my cup of tea. I will admit I read all of it because it was well-written, entertaining and fast moving, and I wanted to find out how it ended. Reminds me in some ways of Stephen King's tales.
