My Immortal Knight by Saranna DeWylde

With his dying breath, Samara Frank’s father bids her to find the Templar Krestien de Godfrey. Only he can protect her and the ancient Sumerian relic they unearthed in a Mayan burial chamber in Belize. It’s a piece of the mythical Adama Tablet and a prehistoric alien god with a cult following called the Covenites will use everything in their power to get the tablet— from the Ark of the Covenant and the Spear of Longinus to Samara’s own damaged sister, Sierra.

Krestien de Godfrey is a man haunted, the bastard son of Godfrey de Bouillon, Duke of Lorraine and Defender of the Sepulcher, he was born only to continue The Blood—an ancient line of divine kingship that goes back to Christ and Cain. A Saracen blade took his left eye and marred his face, but ambrosia from the Grail gave him everlasting life and he’s lived in service to his Order. He can never atone for all he’s done, but Krestien will settle for the quiet peace of eternal sleep after he secures the Adama Tablet.
Samara is a woman of The Blood, the only thing for which this Templar may break his vow of chastity, but she’s the first to look on Krestien’s scarred face with desire. She was raised on tales of his greatness and finds him a hero in the flesh, all the more real for his demons. The Adama Tablet could make her career as an archeologist, but after she sees his suffering, Samara is determined to help Krestien find the peace he seeks.

The call of Blood to Blood is irresistible, but will it be enough to light a candle in the darkness and save them both?
