Musyon and Net Galley let me read this book for review (thank you). It has been published and you can get a copy now.
This delightful story has Mayu finding a mailbox in the woods She doesn't know who put it there but she leaves a letter. Someone writes back to her. They exchange letters until she finally meets the other letter writer. She's excited when she sees who it is but she's disappointed she has go home the next day and she can't write to him from there.
But a solution pops up. His bird friend will carry the messages back and forth. Now Mayu is happier. And she'll be back next summer...
