Publisher's Synopsis
Oliver had always loved mysteries, but he never expected to find one in his own backyard. It all started on a chilly autumn afternoon when he stumbled upon an old, brass key. The moment he picked it up, a strange hum pulsed through his fingers, sending a shiver up his spine.
Oliver gathered the Spectral Sprouts, his friends-Evie, Jasper, and Luna, to show them the key.
And as Oliver held the key tightly in his hand, he knew one thing for sure-this was only the beginning of the Spectral Sprouts' greatest adventure yet!
