A Bear Warrior for Autumn by Summer Donnelly

After a tragedy struck her family when she was 16, Autumn and her six sisters joined the Orphan Trains that went west for families seeking children of their own. Adopted by Magnolia Hartly and her mate Aaron Standing Bear, the girls finally had a home of their own. With this new sense of security, Autumn dreamt of becoming a teacher.
Cameron Two Moons had been seeking his mate since finding out he was a Bear Warrior. He was honored and humbled when his bear recognized the red-haired beauty as their mate. Despite the agony it caused him and his bear, Cameron agreed to postpone their marriage until after Autumn finished her training in Denver.
However, when Oso, Cameron’s bear, begins to suffer, Cameron has to break his vow and go after his mate.
