Zetta is the best potion-maker in the village of Sienna Dunes. Okay, maybe she's the only potion-maker in the village of Sienna Dunes. And maybe her potions don't exactly work like they're supposed to all the time. But when her village is menaced by a pack of illagers, only Zetta can see that the traditional ways won't keep Sienna Dunes safe anymore.

Zetta journeys to her eccentric aunt's workshop outside town to search for an answer and finds a lot more than she bargained for. A mysterious egg hatches into a scaly creature with purple eyes, black wings, and poisonous breath. It can't possibly be the mythical ender dragon . . . can it? And if it is, can Zetta raise it to be the savior her village needs?

The threat of the illagers is growing fast, and Zetta's accidental dragon is growing even faster. With the help of her two best friends and her daydreaming little cousin, Zetta must train the scariest (and scaliest) baby in the Overworld. But when the dragon is fully grown, will it save Sienna Dunes? Or will it spell the village's end?
