Not bad, but not enthralling either. I don't think there was a single likable character in the book (maybe Pogo), and 2 of the brothers were sometimes hard to tell apart. I think there's something there, and I would've enjoyed a longer treatment, if only to develop the characters and their powers a little bit - Rumor's power was intriguing, but I didn't really get it until the end.

Oh, originality points for the first villain we encountered.
