Creeped Out (Monstrum House #2) by Z. Fraillon

Creeped Out

Jasper and his friends are about
to take on their biggest challenge.
They have to find a monster
that's loose somewhere in
Monstrum House . . .
before it finds them.

If they fail, they'll have
their creepy teacher Stenka to
answer to. Or perhaps they'll be
eaten by the monster. It's hard to 
know which is worse.

And you thought your school
was bad.
