From the publisher

“A roller coaster of a book loaded with mayhem, wordplay, burps and farts, and onomatopoeia that will keep readers tuned in and laughing out loud.” –Publishers Weekly (starred review)Who knew delivering the mail could be so perilous? A silly, mischievous story of independence, self-confidence, bravery, and friendship. Just because you’re small doesn’t mean you can’t be brave. That’s the advice Great-Aunt Ada gives Marty Moose for his first day on the job as a mailmouse for the Little Ditch Post Office. With his mailbag in hand, Marty is ready to follow in her footsteps, but filling them proves difficult even with the help of a scrappy and energetic bunny named Nibbles. When a pair of pesky neighbors prevents him from delivering his last package, Marty and his new friend Nibbles must figure out together how to finish the job, even if that means breaking the rules. With lively, funny, and characterful illustrations and a charming narrative voice, this series first is just right for newly confident readers.
