Acedia by Colette Rhodes

Although she’s spent her life in the human realm, Iris has always lived in the shadows.
When the chance to escape presents itself, it seems too good to pass up. Even if it means traveling to another realm—a realm filled with mysterious monsters, no less.
Anything is better than this, right?
Damen is everyone’s favorite prince. Charming, funny, and quick to bring levity to any situation.
But everyone who’s close to him knows that Damen is capable of being so much more. Their opinions have never mattered too much to him before, because why make life hard when it could be easy?
Until he meets someone whose opinion is everything to him. Who has never had life easy. Who believes in him more than he believes in himself.
For Iris, there’s no obstacle Damen won’t face.
