When a shy girl and her dragon-like companion discover their country’s idyllic weather comes at a steep—and secret—cost, they recruit fellow students to defy authority and attempt to spread the truth. Storm beasts and their guardians create perfect weather every day, and Mina longs for a storm beast of her own. But when the gentle girl bonds with a lightning beast—a creature of fire and chaos—everyone’s certain it’s a mistake. Everyone but Mina and the beast himself, Pixit. Quickly enrolled in lightning school, Mina struggles to master a guardian’s skills, and she discovers that her country's weather comes at a devastating cost—a cost powerful people wish to hide. Mina’s never been the type to speak out, but someone has to tell the truth, and, with Pixit’s help, she resolves to find a way to be heard.
