Kat always thought her grandma's stories of Rhaegynne - shapeshifting dragons - were just fairytales. But that all changes when her grandma is killed, and she learns that not only are they real, but she is one.

A prophecy and a curse set in motion ages ago have now turned Kat's quiet senior year into chaos. What was supposed to be a gift becomes a tool for breaking a curse that forces others to serve tyrannical kings who will use them to wage war and destruction across Earth.

But hope . . . is more stubborn than a curse.

Fighting alongside friends new and old, Kat must learn to harness the heart of the dragon in order to break the curse, destroy the kings, and save the dragons. All before succumbing to the curse herself.

Honestly? It'll be a breeze compared to calculus.
