From the author-illustrator of Something Extraordinary and Narwhal and Jelly comes a tale filled with dragons, pickles, friendship, and lots of mail. Liam really wants some mail, so he writes a letter to his mailbox asking for something in return. His mailbox delivers, sending Liam more than he could have hoped for...and how! But as the mail starts to pile up, Liam realizes that the best packages and parcels are even better when shared with friends.
