Darkhaven - A.F.E. Smith In a world where shapeshifters have all the power and are rare the succession is in question. Ayla Nightshade is next in line, although it should be her brother, but he's not shifted, and then her father dies, brutally slain and she's the obvious killer. She goes on the run and her brother investigates with the help of a priestess.

Interesting but a bit predictable.
