Mike McIntyre and his longtime girlfriend, Andrea, are in their early 40s and itching for a break. So they rent out their San Diego home - dog, cat, and furniture included - and embark on a yearlong journey around the world. "We're not out to find ourselves, or even to lose ourselves," McIntyre writes. "We're merely seeking a pause in our routines." But the couple is soon swept up in the adventure of a lifetime.
