Frederik Sandwich and the Earthquake that Couldn't Possibly Be (Frederik Sandwich, 1)

An earthquake? No. It couldn't possibly be. There absolutely shouldn't, wouldn't, and couldn't be an earthquake on Frederik's Hill.

That's what Frederik Sandwich thinks when he's woken by shaking with no explanation on one otherwise ordinary night.

But something has caused it and he's determined to find out what. The problem is no one will talk about it. The entire town claims the earthquake didn't happen. Except, that is, for Pernille, an odd new companion, who has announced, annoyingly, that she won't leave his side until the mystery is solved.

And this mystery is so much more than they bargained for. It will lead the two outsiders through abandoned train tunnels, into hidden library rooms, and to shadowy Municipal Hall in the dead of night, as they strive to figure out what caused the rumblings under their town.
