Miss Hattie Pell has one rule for her new position at Thorn Vale: keep her head down, keep the dowager duchess amused, keep away from the east corridor.
She breaks the last rule her first week.
What she finds there is the Duke of Thornbury with the moon on his shoulders and a wolf's eyes where hers should not have been. Rowan Ashgrove has spent ten years hiding what he is and grieving the fated mate he lost, and he intends to spend ten more. Then Hattie touches his hand in the dark, and the bond tells him the one thing no one in his family has ever told him: a second mate is possible.
Rowan will do anything to keep her away from that. Hattie will do anything to find out why the first mate died.
A steamy regency fated mates romance of corridors, ballrooms, and a wolf who cannot afford to be seen.
