It Sleeps in Me (In Me Series)

Sora is the wise, young High Chieftess of the Black Falcon Nation. For many winters her heart belonged to her husband, Flint, a warrior from a neighboring clan. Flint truly loved Sora, but jealousy drove him to beat men to death for merely casting a longing glance at his wife. Unable to live with his murderous rage, Flint moved back to his mother's clan, divorcing Sora and leaving her forever.
Remarried and fully devoted to her duties as the High Chieftess, Sora tries to bury her memories of Flint. Then, on the eve of war with a neighboring nation, she is visited by Skinner, an old friend of Flint. Skinner tells her of Flint's death, but Sora feels that he carries part of Flint's soul inside him. When Skinner reveals secrets that only Flint would know, and rouses her passion in ways only Flint had, Sora must figure out if this is the clever witchcraft of enemies who want to seize her power and destroy her nation, or the spirit of her one and only true love.
