Overview
Welcome to Grim Falls Academy!
Something weird is happening at Grim Falls Academy... and that's saying something for a school for supernatural kids!
In the thrilling third chapter of the trilogy, curiosity literally unleashes chaos. When Seb uncovers a mysterious, buried box hidden beneath the academy grounds and, despite every warning, decides to open it. The aftermath is pure mayhem: a mischievous troll runs amok, the academy’s grounds sprout into a wild forest, and a wish Seb makes without thinking has consequences he can’t undo. Now Seb, Victor, and Tabby must band together to put things right and uncover the truth behind the box before the school is lost to supernatural strange-ness.
Don’t Open the Box! delivers high-stakes adventure, heartfelt friendship, and imaginative supernatural fun that will captivate middle-grade readers from start to finish.
