It started as an assignment. Everyone in Caitlin's class wrote to an unknown student somewhere in a distant place.

 

There were only ten letters, and fifty kids, but Martin was the top student, so he 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.
