Demetrius - Brethren Origins, #2

Athelyna Des Moutiers has lived the better portion of her years in a convent, isolated from the harsh realities of her world, and has dedicated her life in service to a higher calling. When her father dies, her manipulative older brother negotiates a betrothal contract to one of the King's knights, surrendering her to a creature utterly foreign-a man. A wedding present, an ancient brooch with mythical powers, foretells a future she cannot deny, so she accepts her fate.
Can she win the love of her husband, a stubborn brute equally resistant to marriage? Demetrius de Blackbourne is a Nautionnier Knight, a pious man, and a virgin who, much like his bride, has vowed to devote himself to divine endeavors, and his plans do not include a wife. When he is tasked with settling a troublesome region, and installing the King's new garrison, he neglects the most important charge of all-his lady.
But the gentle spirit and quiet strength of Athelyna manifest a temptation he can neither ignore nor deny, and Demetrius finds himself fighting for the one thing he never thought he would want-her heart.
