Beware a tooth fairy queen scorned in this, the third chapter book of Academy Award winner William Joyce’s The Guardians series. There’s a lot more to this tooth-swiping sprite than meets the eye! When last we heard, the Guardians were resting easy with the knowledge that the children of Santoff Clausen were finally safe from Pitch’s dastardly plans.

But is it all a ruse, a scheme, a lull the evil Nightmare King has deviously concocted?

Whatever Pitch’s plans, what he doesn’t know is that there’s a new Guardian in town, and she’s not the type to forget old grudges. Actually, she’s not the type to forget anything–because this Guardian is none other than Toothiana, the Tooth Fairy herself. She’s fierce and fast and crossing her will lead to a multitude of troubles. And, it turns out that, well, all those teeth she has been collecting? They contain memories. The forgotten memories of childhood…including the memories of how to fly. Young Katherine is hopeful that these memories might help her to remember her parents. The Guardians hope they’ll offer even further protection from Pitch.

You can see how this information would be invaluable to our heroes. But it could also be invaluable to Pitch…
