Orpheus

Science thinks it's shattered the barrier between life and death, but it has only opened the floodgates. Stop meddling with the affairs of ghosts and close the doors before something follows you back through. You should have left some secrets buried, because now they won't go back to sleep without a fight. It's called projecting, the ability to separate the soul from the body and interact with ghosts. It's a multi-billion dollar enterprise for companies like Orpheus Group, which offers its services to public and private interests. It's also a portent of dark things to come. Orpheus is a new type of game, a ghost story for ghosts told in a six-book limited series.
