He knows every student's name. He is always first in. He never leaves.
Thornhill School looks exactly like any other school. Students attend classes. Teachers assign homework. The principal walks the halls, greets students by name, and keeps everything running smoothly.
But Alex Carter has noticed something wrong.
The principal is in two places at once. Then three. His office light burns past midnight every night. He knew a student was sick before she did. He has never been seen eating, drinking, or carrying so much as a folder. And the faculty photograph from thirty years ago shows the same face, the same posture, the same unsettling stillness that Alex sees every single day in the corridor.
Alex and the group begin to investigate. What they find in the school's oldest records reaches further back than anyone expected, and points toward a truth that is stranger, older, and more complicated than any monster they have faced before.
Because not everything hidden at Thornhill School is hiding from the students.
Some things have been here since before the school was built.
And some things cannot be stopped.
The Principal Who Never Slept is the seventh standalone novel in the Thornhill School Mysteries series. Each book can be read independently. For ages 10 to 15.
