Expedition of Love by Jo Barrett
Doctor Stephen Baxter, an up-and-coming scientist in the world of paleontology, collides heart first with the unconventional Miss Kristina Peterson. Her extremely vocal views on women's suffrage, and her exceptional knowledge of paleontology leave the stoic doctor dumbfounded. But he knows he is not the man for her. Having no desire to marry, Kristina Peterson never gave much thought to sex other than the scientific aspects until now. Thrown together by her matchmaking father on a paleontology expedition, she discovers that beneath Stephen Baxter's stoic exterior lies a handsome and extremely interesting man. A man she decides would be the perfect choice to show her the wonders of intimacy--without resulting in matrimony, of course.
