The first thought that crossed her mind was: hidden room!
There must be a secret room inside the library, because it's almost impossible to hide him in plain sight. If she did, then what was the whole point of hiding him!
Senja tried to push every bookshelf hoping it would move. Her third attempt found a small, almost invisible hook attached to the wall beside the bookshelf. She leaned over to reach it.
After a 'click' the bookshelf beside her moved revealing a small passage. Senja felt a mix of excitement and eeriness. **Who knew what would be inside the room?! **
And yet, Senja stilled her heart as she stepped inside.
The moment she stepped in she could feel the damp smell lingering in the air. Even though Senja saw there were three air vents on the side of the wall, they're insufficient in this closed room.
