Strange Changes: Cernunni and Ursuma

From publisher blurb:

There is no perfection in this world, and even the most consistent of cycles break. Predator and prey, hunter and hunted. Light and darkness wage an eternal war, raging from equinox to solstice and back. This is a world of cycles- and wherever they break, when the delicate balance is being distubed, the world changes, growing stranger and stranger.

This book contains:

The Cernunni- elusive weredeer who share an ancient bond to the Uratha since the times of Pangaea, always in danger of getting corrupted by their own death into a cannibalistic wendigo

The Ursuma- plant shifters born from mutated Ghost Wolves, who have their Essence devoured by a poisonous wolfsbane.
