The Maleficent Faerie by Rebecca F. Kenney

A spicy, Fae Sleeping Beauty retelling with a male version of Maleficent, a dying realm, and intriguing twists on the old tale.
When Malec, the Void King, attacks Princess Dawn’s carriage, her Fae bodyguard Aura switches places with her. Glamoured as a human, Aura must fool Malec into thinking she’s the Princess he cursed 25 years ago. Relentless and powerful, but with a vulnerable side he hides from others, Malec begins to crave Aura’s respect as much as he craves her body.
