Lady Arryn knows the rules. 

A highborn lady does not use fire magic. She does not ride into the Barrier Mountains alone. And she absolutely does not fall through a hole in the magical barrier between her refined kingdom and the prison where their enemies have been trapped for centuries and then land at the feet of a pale, frostbitten sentry who greets her with a sword to her throat.

But the Lands Below don't follow her rules. 

And the deeper Arryn travels into this dying frozen world, stalked by monsters, slowly poisoned by its darkness, and dangerously close to Rowan Undervale, the most maddening person she’s ever met, the more she wonders if the life she’s trying to reclaim is the life she actually wants.

Rowan Undervale is nobody's hero.

He has deadly magic that’s made him an outcast, a brother he'd burn down the world for, and absolutely no interest in whatever problem just fell out of the sky and landed in his forest. The lady from the Worlds Above is someone else's disaster. He'll hand her over to the king and be done with it.

He's said this. Out loud. Several times. 

But his brother Phaedron isn't listening. So Rowan agrees to escort the lady to safety. It's a favor. It's temporary. 

It's definitely not going to become the most dangerous thing he's ever done. Because the only thing more dangerous than his magic or the void threatening their world would be falling for someone the king would very much like to use as a weapon.

Previously published as Heart's Rescue, this steamy, standalone romantasy is perfect for readers who love opposites attract, forced proximity, "he treats her like an equal," character growth, dual POV, and a guaranteed HEA.
