The Mystery of the Basement Rumble

A strange rumble. A forgotten basement. A mystery only three kids can solve…
When a weird buzzing noise echoes from the old house at the end of Maple Street, 14-year-old Alex and his best friends Sam and Jess can't resist investigating.
What they find is more incredible—and more dangerous—than anything they imagined: a hidden passageway, a tiny secret door, and a mysterious invention buried in the dark.
As the strange machine grows louder, threatens their town, and shakes the walls around them, the trio must rely on bravery, teamwork, and quick thinking to uncover the truth.
Can they fix the invention before it's too late… or will Willabrook be shaken apart?

A fun, exciting mystery adventure perfect for ages 8–12!
