Hold Me Fast by Jude Knight

She has paid for her fame with her heart and her dreams. What must she pay for peace and love?

Childhood sweethearts Tamsyn Roskilly and Jowan Trethewey are ripped apart when her mother and his father conspire to sell Tamsyn to a music-loving earl. He promises to make her a famous singer, and to keep her from Jowan.
Hold Me Fast starts seven years later, when Tamsyn has become Tammie Lind, a sensational singing success. Jowan, now baronet in his father’s place, hears she has returned to England after a lengthy and successful tour of Europe and beyond. He travels to London to speak to her, but the earl continues to stand in their way.
However, Jowan discovers that Tamsyn has become addicted to drugs and alcohol, supplied by the earl who has seduced, debased, and abused her. Their childhood romance may be over, but now he owes her a rescue.
As he and his friends nurse her through withdrawal and help her make a new life in their home village, Jowan and Tamsyn fall in love all over again. But Tamsyn does not believe she is worthy of love, or that Jowan can truly overlook her past. And the wicked earl is determined to take her back.

It will take the help of their friends and their entire community for Jowan and Tamsyn to finally prevail.
