For as long as Erin can remember her visits to see her uncle at Dorsey Castle in England, always held nightmares. She decided it must be the thick castle walls.
Only on this visit the nightmares become her reality. Erin finds herself back in time, living all the dangers that come with becoming her ancestor and they aren't going away with the sunrise.
Falling in love with the Irish nobleman her ancestor refused to marry doesn't come with a guidebook. Erin fears she will never survive the villain that comes with the castle, the master at arms, one that wants her dead.
