Prince in Disguise by Tavia Lark

Rakos isn’t really a farmer. Bellamy definitely isn’t a minstrel.

Sheltered, sickly Prince Bellamy always longed for adventure—but not like this. Captured in enemy territory, Bellamy’s true identity will get him killed, or worse. When his smoking-hot fellow prisoner asks who he is, Bellamy claims to be a minstrel.
Even though he can’t carry a tune to save his life. He panicked, okay?
Rakos was the rising star of the Draskoran dragon riders until betrayal landed him in chains. He knows two things for certain: he can’t trust anyone, and he wants his dragon back. When a pretty, fragile minstrel asks who he is, Rakos claims he’s a farmer. When Bellamy begs for help reaching the border, Rakos refuses.
Until Bellamy reveals his magic is exactly what Rakos needs.
Stormy nights, pursuing soldiers, and deadly masquerades forge Rakos and Bellamy’s unlikely partnership into something more. Something exhilarating. Rakos treats Bellamy like a person, not a weak, untouchable prince, even as he protects him.
But Rakos’s enemies are circling in, and that very protection might be Bellamy’s undoing.
