Five dog-loving autistic kids have a mission to accomplish—and a mystery to solve—in a delightful ode to idiosyncrasies from the author of All the Small Wonderful Things.

Eleven-year-old Oli is spending his spring break at Heroes Club, where autistic kids like him can build friendships and learn about their emotions. Sounds fun, right? No. Nothing like a week of forced socialization and emotional learning to ruin summer break. Oli just wants to be home, where it’s familiar, not so boring, and he can play games on his phone. But when Oli and the other kids at the club see a stray dog who keeps disappearing into a soon-to-be-demolished building across the street, they hatch a daring rescue plan to save the dog before it’s too late. It’s going to take bravery, some seriously smart teamwork, and a few broken rules to make a difference. For Oli and his new friends in the Heroes Club, making use of their unique talents and perspectives—together—will be a challenge. But doing the right thing is entirely worth it. The Unlikely Heroes Club is a celebration of friendship and community that is sure to make your heart sing.
