Endicott heirs have always taken Stark maidens for their brides....
A blood oath forged eight centuries ago promised Helen Stark to Lord Weathersky Endicott in marriage from the day she was born. The nineteen-year-old orphan bride-to-be arrives at Cragmoore Castle eager to meet her betrothed, sensibly trading love for the security of an arranged marriage.

Weathersky has other ideas—and a secret power. The handsome, brilliant Endicott heir is a warlock with mastery over everything but love and he longs to break free of the castle and live a mortal life. Helen resolves to help him without realizing the consequences of breaking the oath. Eight hundred years of supernatural rule will not be overthrown without a fight.
