Sleepwalker

From publisher blurb: Sleepwalker: When librarian Ida Merrid sleeps, she dreams of exciting heroes, angry gods, and adventurous thieves. She doesn't know it, but they're all her. Ida was exposed to the Silver Storm and when she sleeps her new powers transform her into a form that allows her to act on her hidden desires, fears, and frustrations! Maybe all those villains the heroes have been dealing with lately are actually just Ida sleepwalking!
