Lord of Sherwood (The Guardians of Sherwood Trilogy #3)
Laura Strickland

Anwyn Montfort has fled disgrace in Shrewsbury and come to Nottingham at her father's bidding. He wishes her to make a good marriage and settle down. But the wildness that possesses her refuses to quiet. She knows she's been searching for something all her life, but not until she glimpses Curlew does her spirit begin to hope it has found its home.
Only the magic of Sherwood can bring them together, and only their union can complete the spell woven so long ago...
