Silent Love — Barbara Goss

Caroline is desperate to reach Oregon and find her only living relative. She persuades Simon, a man traveling on a wagon train, to let her pose as his wife. As they face and overcome capture by Indians and other dangerous adventures along the Oregon Trail, Caroline and Simon bond as friends. When they reach Oregon and Caroline's Aunt Hattie, they go their separate ways as agreed upon at the beginning of their farce. Soon, they both realize that parting was a mistake. Did love come too quietly for them to recognize it--and have they lost their chance? Will they find each other again? Clean romance.
