Lenna at the All Thing (Book 3 of Lenna's Story)
by James Comins
The flood of magic is dammed up--for now. Lenna returns to Asgard to find that the gods have gathered for a great meeting. But since Lenna accidentally released a certain evil shapeshifting redheaded Norse god into the world, she can't be sure of anything or anyone. Not even herself.
Oh, and Binnan Darnan totally has a boyfriend.
