Wendigogo

Morty didn't intend to become a cannibal.

Lately he hasn't felt like himself, and his friends are concerned.

Something has been eating his neighbors.

A treacherous shaman and a psychotic water panther are urging Morty to unleash his carnivorous side. A relentless Bigfoot hunter, an arrogant oil company, and sinister squirrels are only making Morty's life crazier. 

Morty was happy being an average nerd. How is a snarky bookseller-turning-wendigo expected to keep his sanity and his girlfriend in all this?

Book One of The Reluctant Wendigo.
