Paige Newsom loves her college professor job, visits her mother regularly, and has three successful daughters. She had no plans to upend her life again now she's settled from her divorce, but is thrust into co-teaching a course that includes a three-week international field study. Paige can think of many reasons to not go, including the dazzling Australian biologist Professor Jack King. As the two co-professors lead the rigorous program together, first on campus, then in beautiful Tanzania, Paige's biggest challenge will be resisting the undeniable chemistry she feels when she s with him.
