Jessica Day George's Friday with the Wizards
The fourth book in the Castle Glower series is pretty much as delightful as the first few, as the gang has to raise some griffins, battle an evil wizard, and grow closer as a family. Protagonist Celia is mildly bratty for part of the book, but works her crap out, and I really appreciated that we finally get to know more about her mother (who is very cool). Nice action, cute animals, and I'll be waiting for the next one. A-.
