Molly Phillips' new gig in Chicago is in an old waterfront building that turns out to be haunted by the ghost of a drowned boy. Her daughter, Fiona (Fi), who seems to always investigate the paranormal, becomes curious when the drowned boy keeps appearing to her.

Fi meets a 9 year old boy who's created a troublesome entity (or tulpa) by concentrated thought and this entity is very dangerous.

Fi tries to contact her dad through a real medium who spends his time debunking fake mediums and has no interest in using his own talents.

A Halloween gig in a strange New England town called Rhiannon turns into a nightmare when Fi discovers that the spirits of the dead walk the night on Halloween and drag any living beings back with them.

Fi decides to go live with her aunt for the school year in order to forget the supernatural and resume a normal life, at the same time that Annie Phelan, a family friend joins the tour. Fi learns that Annie has a supernatural aura around her too, especially when Fi's now blank ring suddenly sprouts it's designs once again when placed on Annie's finger.
