"Izzy's a bass-playing werewolf. Geraldine's the ghost of an amazing jazz pianist. Delilah's the meanest drummer in town. They'd be the perfect trio to win the Battle of Bands...except Geraldine can't play a solo since she passed away, and Izzy and Delilah are at each other's throats at every opportunity. Can they work through their problems to win the competition, or will they be defeated by Delilah's ex-band and their villainous frontman, Dylan?"-- Provided by publisher.
