I am reading the Demonata series. I began reading because it was recommended to me by the librarian. The plot is fast paced but easy to keep track of. Demons exist and there is a disease in the family that turns you into a werewolf. The only way to cure the disease is to confront lord loss at a game of chess. While a person of your choice fights off his minions. If you lose you die. If you win you have to go into the demons realm and fight lord loss. Once again if you lose you die. But if you win you go free and the family member who is infected becomes cured. Only the magical families know about the demons and werewolves.
