Dragons and their riders protect Arethia's borders and keep peace within the land, along with the mages who work alongside them. Nobody knows why, but only women can bond with dragons to be their riders. But now, the dragons have been kidnapped by a mage who wants to change that, and the remaining dragon riders have to find out where he's taken them. Arethia's safety is now left to the mages, and Karume mages using the forbidden bound magic begin creeping into Arethia while the search for the missing dragons is stalled. Can Tesa and her friends bring the dragons back to Arethia before it's too late? Will the Karume change the way magic is used in Arethia forever?
