A castle has appeared behind Briar Glen Middle School.
Miles Calder knows three things about that.
One, it was definitely not there yesterday.
Two, no one else seems nearly worried enough.
Three, when his locker opens into a stone corridor and someone inside says, Investigator Calder is late, the school day is probably not going to improve.
Miles has already survived goblins, missing keys, raven courts, stolen shadows, and one very judgmental bird. But Castle Morrowmere is not just another Grimhollow problem. It is old, dangerous, and somehow tied to Miles's grandfather, Arthur Calder.
Soon, classrooms begin changing shape. Lockers become doors. Maps refuse to finish. An apprentice investigator named Elara Venn arrives with an official accusation: Miles Calder is the primary suspect. And somewhere inside the castle is a room that should not exist, a floorplan that is lying, and another lock the Locksmith wants opened.
Now Miles must solve the mystery before Briar Glen Middle becomes part of Castle Morrowmere forever.
And before the thing under Maple Street wakes up next.
A spooky-funny middle-grade fantasy mystery for readers ages 9-12.
