Who's Been Sleeping in My Grave? — R.L. Stine

A boy suspects his substitute teacher is hiding a sinister secret in this second book in the Ghosts of Fear Street series from the master of children's horror, R.L. Stine -- now with a reimagined look!

Do you believe in ghosts? Don't say no until you take a walk down Fear Street. Past the woods, where no birds sing. Past the lake, where something lurks beneath the water. Past the cemetery, where everyone is dying to meet you.

Zack Pepper thinks there is something very wrong with his substitute teacher. She's super creepy and seems far too interested in him. But no one else seems to notice anything amiss. Zack is going to have to uncover the truth on his own -- but will investigating prove to be a deadly mistake?
