My Chew-Toy, The Godfrey.

Juanita Josephine, or JJ as she likes to be called, is a different breed of shifter. In some ways, she's similar to the gypsies that we all know and love. She can half-shift whenever she pleases and fully shift if she wish it. JJ has extreme speed and strength, but there's one thing that truly makes her stand out from the rest of her kind.
