After reading Consider the Octopus a few weeks ago, I started wondering whether other middle grade books set on a ship exist. I could think of a couple of others right away, but I was stumped after. I turned to my Twitter community of readers, teachers, and librarians and they showed up with fantastic recommendations of tween books set aboard sailing ships. I’m happy to share some top picks with you!

The Best Middle Grade Books Set on a Ship
Here are 25 of the best middle grade books set aboard a ship:
The Last Mapmaker
Published: April 12, 2022
In a fantasy adventure every bit as compelling and confident in its world building as her Newbery Honor Book A Wish in the Dark, Christina Soontornvat explores a young woman’s struggle to unburden herself of the past and chart her own destiny in a world of secrets. As assistant to Mangkon’s most celebrated mapmaker, twelve-year-old Sai plays the part of a well-bred young lady with a glittering future. In reality, her father is a conman—and in a kingdom where the status of one’s ancestors dictates their social position, the truth could ruin her. Sai seizes the chance to join an expedition to chart the southern seas, but she isn’t the only one aboard with secrets. When Sai learns that the ship might be heading for the fabled Sunderlands—a land of dragons, dangers, and riches beyond imagining—she must weigh the cost of her dreams. Vivid, suspenseful, and thought-provoking, this tale of identity and integrity is as beautiful and intricate as the maps of old.
Consider the Octopus
Published: April 5, 2022
Jeremy “JB” Barnes is looking forward to spending the summer before seventh grade hanging on the beach. But his mother, a scientist, has called for him to join her aboard a research ship where, instead, he’ll spend his summer seasick and bored as he stares out at the endless plastic, microbeads, and other floating debris, both visible and not, that make up the Great Pacific Garbage Patch.
Miles and miles away, twelve-year-old Sidney Miller is trying to come up with an alternate activity worthy of convincing her overprotective parents that she can skip summer camp.
When Jeremy is asked to find the contact information for a list of important international scientists and invite them to attend a last-minute Emergency Global Summit, he’s excited to have a chance to actually do something that matters to the mission. How could he know that the Sidney Miller he messages is not the famous marine biologist he has been tasked with contacting, but rather a girl making podcasts from her bedroom―let alone that she would want to sneak aboard the ship?
