Smolder by Sharon Ashwood

A prince. A prisoner. The last embers of hope.

Leena is a fae and a fire dancer, as wild as her mountain home. But war with the Shades has crushed her tribe, and she is forced to use her powers for her captors’ entertainment. She obeys to protect her family, until the Shades enslave her young brother in a nightmarish spell.
Rich, arrogant, and devastatingly handsome, Morran is feared as an ally of the Shades. Known as the Phoenix Prince, he is a prisoner of a different kind, cursed to forget his bloodline’s legacy of magic. His familiar is the firebird, but it has been stolen—along with his memories, his power, and his sanity.
If Leena can heal the prince, she has a chance to rescue her brother—but it’s been centuries since Morran was cursed. Can she find the key to warming his heart again? And once the Phoenix Prince is free, who says she’ll be able to tame him?
