Witch Got Your Tongue -- Livia J. Washburn

This is the first book in a new series by Livia Washburn. At least it had better be a series, considering the cliffhanger ending. I'd kind of like to know what happens next.

Aren McAllister is the witch of the title, though she's had very little experience of being one. That's because she stutters, and witches who stutter can't cast spells. But, like Mel Tillis, she discovers that she can sing without stuttering and that spells can be sung. Complications, as you might expect, ensue, but probably not the kind of complications you're thinking of. As it turns out the stuttering isn't what Aren thought it was, and neither is anything else about her life.

If you want more, you'll have to read it yourself. It's very fast and funny, so it won't take you long, and you'll be glad you did.
