King of Fire and Flames by Juno Heart

Arrowyn Ramiel, the King of Storms and Feathers. Fae scum. Liar. Unforgivable betrayer and breaker of fragile hearts…. Or is he?
LEAF:
Trapped in the Sun Realm, I have no choice but to accept King Azarn’s offer and fight for a chance to survive. Only then can I turn my vengeful eye upon the fae who crushed my heart—the betrayer, Arrowyn Ramiel.
When Arrow arrives at the Fire Court, I learn things might not be as they first seem. Old friends and new enemies’ allegiances aren’t clear, and I must unravel a tangled web of lies and decide if I can trust the Storm King again—not only with my life, but my heart, too.
