To Break a Dark Cage

Why these tropes fit

A dark fantasy romance in which Gwen, captive of the demon-prince Mordred she still loves, must win back his trust after she sided with his enemies in Avalon’s war. Mordred anchors the story as a brooding, emotionally repressed, morally gray anti-hero torn between rage, pride, and lingering passion, while Gwen returns to the island newly empowered to avert destruction. The central dynamic plays out as an enemies-to-lovers, captive-romance slow burn laced with angst and betrayal, fueled by explosive chemistry and sensual tension.
