About This Book
The soft shuffle of footsteps fills the quiet halls, but something smells strange—like mystery mixed with a hint of secrets. Everywhere Josh and Jenny look, nearly identical substitute teachers are asking odd questions and scribbling down every word. When their favorite teacher suddenly vanishes, the twins feel a mix of worry and determination—they have to uncover the truth, but what will they discover?
