A War of Three Kings by Rosa Heart

He stole her heart then broke it with his lies and betrayal. She must choose between forgiveness or leaving him to rot in her father’s prison.
Aldrin was revealed to be everything Keira fears from the fae; dangerous, possessive, and toxic enough to steal a human woman. He has been hunting her for decades to keep her as his slave and consort—except, that story makes little sense to Keira. Not when he let her leave him and his realm behind forever.
Before Keira can decide if she will allow Aldrin back into her heart and her bed, war arrives at her door. The mad king Finan ravages his own kingdom to get his clutches on Keira and he will stop at no atrocity to repossess her.
If he succeeds, it won’t ruin only her life. The North will fall. Her family will be destroyed.
Keira’s only protection, the single reason the lords of the North stand with her family against their king, is because she has dedicated herself to the temple. To ravish her would be sacrilege—except, she might want Aldrin to ravish her.
As Aldrin fights for Keira’s freedom, like the feral fae he is accused of being, their passionate flame threatens to reignite. If the secret is discovered, it may very well burn them all.
