"In the interdimensional maelstrom of New Jerusalem--what New York used to be before it went to hell, literally!--the agents of Libra quietly keep the lid on the paranormal pressure cooker. When agent Klaus Reinhertz tracks the source of the super-drug Angel Scale, he is drawn into a deadly game with a mob boss from the Beyond: Win and have your dreams come true, lose and have your mind absorbed by the alien godfather!" -- from publisher's web site.
