Sometimes you read a book and enjoy it while reading, only to find it falls apart when you think about it later. The inverse happened to me with Philippa Ballantine’s Geist. I enjoyed it, and then the more I thought about it, the more I found to appreciate.
Geist is a secondary-world fantasy, set on the continent of Arkaym. The residents of Arkaym fear the geists, powerful otherworldly spirits that can enter the physical realm and possess people.
