Saga of the Unfated Tome 1
A Fate Inked in Blood

Trapped in an unwanted marriage, Freya dreams of becoming a warrior - and of putting an axe in her controlling husband's back. But those dreams become a nightmare when he makes a deal with their fanatical ruler, and she's forced into a fight to the death. To survive, she must reveal her deepest secret : she possesses a drop of a goddess's blood and magic that will unite their nation beneath the one who controls her fate.
Believing he's destined to be king, the ruler binds Freya with a blood oath and orders his fierce but charming son to train her to fight, to control her magic... and to make sure no one lays a hand on her. But the greatest test of all may be resisting her forbidden attraction to the son of her enemy.
