A fast-paced middle school mystery about a hidden agreement that could change everything.
When a sealed annex at Brackenridge Middle School is quietly reclassified, most students ignore it.
Tamsin Sloane does not.
A cracked courtyard slab.
A buried ledger.
A trust agreement no one was supposed to see.
What begins as after-hours curiosity turns into a race to uncover a secret property deal tied to land the school was never meant to control. The deeper Tamsin, Callum Ridge, and Ravi dig, the clearer it becomes: someone powerful wants the truth to stay buried.
Now they are facing:
- A sealed school record
- A hidden land transfer clause
- A rushed administrative hearing
- And adults who are not telling the whole story
Every clue raises the stakes.
Every discovery brings consequences.
Perfect for readers ages 9-14 who love middle school mystery books, school-based mysteries, and smart kids uncovering secrets adults try to hide.
The Secret Under the Annex is part of the Middle School Mystery Series-stand-alone, high-intensity mysteries featuring new schools, new characters, and new secrets in every book.
