Välikirja: The Wyvern's Pact
[English] A deal with an ice-breathing wyvern is something you don't usually come across, but when the whole castle is against you and your best friend, it's the only thing that might keep you from being burned to death. So when Koshka, a student from Aethelgard, discovers that the whole school plans to burn her best friend, she's forced to put her trust on Aiden, the wyvern-turning man, who insists on making a deal with her for a reason she doesn't know.
They successfully save her best friend, Safia, from death. But when they arrive at his castle, things don't go the way she expects them to. Aiden turns out to be a man she has never expected him to be, and does something she has always feared. As she stays in his castle against her will, she needs to survive everything he puts her through every day, while keeping her sanity intact. And she discovers that even for a strong-minded girl, that's serious work.
