About the title
After breaking up with her boyfriend, Kate Forster decides to move in order to start over with a clean slate, and also to be closer to work. She leaves a letter in the mailbox for the next tenant, explaining a few details. The new tenant turns out to be Alex Wyler — a lonely architect whose father built this beautiful house. He reads the message but cannot understand why what Kate describes doesn't match reality. This prompts Alex to write back. After several days of correspondence, the characters realize they are living in different times: he in 2004, she in 2006. And only the mysterious mailbox serves as a bridge connecting them.
