The Case of the Library Lock-In Secret : The Anna & Ava Detective Agency, Book 12
Overview
Locked in overnight.
A missing key.
And a secret hidden behind the shelves.
When Anna and Ava attend a library lock-in, the night takes an unexpected turn when a historic brass key disappears from a display case-without a single sign of damage.
No broken glass.
No forced entry.
Just one careful removal.
As the library doors lock for the night, the suspects are limited-but the mystery grows deeper. A shifted bookshelf. A hidden door. And a truth someone isn't ready to share.
But Anna and Ava don't guess.
They confirm.
In this thoughtful mystery, the sisters uncover more than what was taken-they discover why it was taken, and how even good intentions can create confusion when the full story isn't told.
Perfect for readers ages 7-12 who love:
- Smart girl detectives
- Realistic mysteries in familiar places
- Stories about truth, trust, and teamwork
Because sometimes solving the case...
means understanding the story behind it.
