Asperfell

Even as an old maid of twenty, Briony has no interest in the rituals of the court, especially when her kingdom's ruler has an obsession with brutally eliminating anyone who can use magic from the land. When Briony is arrested for showing signs of magic, she evades a death sentence by jumping through the gate to Asperfell, an enchanted prison built to hold the darkest and most dangerous of Mages.

Trapped amongst the hopeless, the violent, the deranged, Briony does her best to stay alive while also desperately trying to understand her new powers. The only way to get back home is to rescue the true heir to the throne, the Mage prince Elyan, who'd been wrongly accused of murdering his father. When she finally finds him, he's nothing like the regal, courageous prince he once was: Elyan's time in Asperfell has made him cynical and jaded.

As they journey together, trying and failing to resist the undeniable attraction between them while fighting incredible terrors, they'll regain the hope of saving their kingdom and come together to fight a tyrant who would destroy all the magic in their world.
