Spirit of the Otherworld completes the Rowan of the Wood fantasy series with a dangerous quest and one very angry (not to mention demented) Vampire Witch. Forced to split into two factions, The Freak Squad goes on some fun, albeit unbelievable, adventures as they scramble to decipher Cullen's trust and figure out how to defeat the evil witch Fiana. The countdown to Samhain is on, and if they don't get Rowan out of Cullen in time, it could mean the end to them both.
