A loose brick. A hidden map. A secret tunnel under the school.
When Maya and her friends discover an old map inside the Riverside Middle School library wall, they think they've found a forgotten piece of school history. Then they uncover a basement door that leads to a secret tunnel no student was ever supposed to find.
Inside the underground passages, the kids follow hidden clues, track mysterious boxes, and uncover evidence tied to a long-lost art theft someone desperately wants to keep buried.
Maya wants answers.
Aisha wants action.
Josh wants proof.
Marcus wants everyone to stay safe.
But the deeper they go, the more dangerous the mystery becomes.
Some secrets were buried for a reason.
And this one won't stay hidden much longer.
The Tunnels Beneath Riverside is a standalone book in the MG Mystery Series by Allie Shad, perfect for readers ages 9-14 who love middle school mystery books, kid detective adventures, secret tunnels, hidden maps, student detectives, and fast-paced clue-based mysteries.
