It started as an assignment. Everyone in Caitlin's class wrote to an unknown student somewhere in a distant place. Martin was lucky to even receive a pen-pal letter. There were only ten letters, and forty kids in his class. But he was the top student, sohe got the first one. That letter was the beginning of a correspondence that spanned six years and changed two lives. In this compelling dual memoir, Caitlin and Martin recount how they became best friends -- and better people -- through their long-distance exchange. Their story will inspire you to look beyond your own life and wonder about the world at large and your place in it.
