Spell Bound is the 12th book in the Women of the Otherworld series. It's nice to be able to follow a series with lots of characters who can switch from a main role to the supporting cast. This is a great series.
Savannah offered a desperate bargain and someone appears to have taken her up on it. Her powers have vanished. She's not dealing with being a normal mortal well. There is a lot going on in this story and the ending is good, but it's not a conclusion, it's just a beginning. Very highly recommended.
