Query: Good premise, but lags somewhat

This Harry Potter-esque book does have a pretty good plot, I'll give you that. It also has some interesting, funny, fast-paced parts with good dialogue. Unfortunately, I found that it lagged in many places, as Yolen's books tend to do. I often found myself skipping pages or putting the book down after readng 1-2 pages because I was bored. If you ordinarily enjoy Jane Yolen, then you would probably like this, otherwise I would pass.
