Sometimes, every deal is a bad hand. Mattie's oath to Morta is under siege, and now there's hell to pay. With an immortal sorcerer and his demon on the rampage, and a feud about to explode between the lycans and the witches, only a bad deal with the dead can help Mattie lift a centuries-old curse and rescue Rhys. But neither Mattie nor her friends suspect there's a deeper, darker plot that threatens the lives of everyone in Shore Haven. For Mattie Blackman, the Hand of Fate may be a very bad deal indeed. Cosmic Groove is the fifth book in the Hand of Fate urban fantasy series.
