25 Middle-Grade Books Set in the Summer

Ah, summer. Now that we’re wading into fall, I figured it’s a good time to share these middle-grade books set in the summer. There’s just a freedom about summer. Growing up in a tropical country meant it was warm all year round, but for us summer was about the time AWAY from school. It was in the late nights and sleep-ins and time with friends and nothing on the schedule. That’s what these middle-grade books set in the summer encapsulate.

However, it’s not all fun and games. While one or two of these books are set in summer camps, I didn’t focus on those, because I have an entire book list on middle-grade summer camp books. On this list you’ll find heartwarming coming-of-age stories, mysteries, family stories, and hard stories about parents and grandparents with mental health issues and death and grief. But overall, the feel of summer is strong in these books!

Let’s get started. Click on the book covers to go their Amazon pages.

The Battle of Junk Mountain

Middle-Grade Books set in summer - the battle of junk mountain

Twelve-year-old Shayne Whittaker has always spent summers on the Maine coast, visiting her grandmother Bea and playing with her BFF Poppy. Both Shayne and Bea are collectors, in their own ways: Shayne revels in golden memories of searching for sea glass and weaving friendship bracelets with Poppy, while Bea scours flea markets for valuable finds, much of which she adds to a growing pile in her house that Shayne jokingly calls Junk Mountain.

This summer, though, everything has changed. Poppy would rather talk about boys than bracelets, and Bea’s collecting mania has morphed into hoarding. Only Linc, the weird Civil War-obsessed kid next door, pays attention to her. Turns out Linc’s collected a secret of his own, one that could enrage the meanest lobsterman on the planet, his grandpa. What begins as the worst summer of Shayne’s life becomes the most meaningful, as she wages an all-out battle to save her friendships, rescue her grandmother, and protect the memories she loves the most.

Wherever the sharks led, Lucy Everhart’s marine-biologist mother was sure to follow. In fact, she was on a boat far off the coast of Massachusetts, collecting shark data when she died suddenly. Lucy was seven. Since then Lucy and her father have kept their heads above water–thanks in large part to a few close friends and neighbors. But June of her twelfth summer brings more than the end of school and a heat wave to sleepy Rockport. On one steamy day, the tide brings a great white–and then another tragedy, cutting short a friendship everyone insists was “meaningful” but no one can tell Lucy what it all meant. To survive the fresh wave of grief, Lucy must grab the line that connects her depressed father, a stubborn fisherman, and a curious old widower to her mother’s unfinished research on the Great White’s return to Cape Cod. If Lucy can find a way to help this unlikely quartet follow the sharks her mother loved, she’ll finally be able to look beyond what she’s lost and toward what’s left to be discovered.
