Sid Jones successfully freed a pirate ghost named Bones from spending eternity trapped in a graveyard prison and, along with her best friend Zen, helped him complete his unfinished business on Earth. But there are plenty more ghosts who are trapped in the in-between like Bones was. While they try to help the others, Sid, Zen, and Bones will have to avoid being caught by Old Scratch, the creepy specter who guards the prisoners. When their ghost friends start disappearing bit by bit, the pressure is on to free them all before they’re turned to wraiths, never to be at peace. But Sid soon finds out that Old Scratch isn’t the only terrifying ghoul guarding the prisoners. With a mysterious figure tracking her every move, Sid will have to find the power within herself to save her friends—before she gets turned into a ghost, too.
