PREORDER NOW!

A boy’s failed science experiment develops a mind of its own in the eighth book in the Ghosts of Fear Street middle grade series from master of horror R.L. Stine—now with a brand-new look!

Al isn’t impressed with his new chemistry set. The stink bomb he made doesn’t explode. And it doesn’t smell. It just sits there.

Then it starts to ooze. It oozes all over the cat. It oozes all over Al’s best friend. And everything the ooze touches seems different somehow, dumber—as if the ooze were making their brains turn to ooze.

Al doesn’t know what to do when the ooze starts coming for him. Can he find a way to stop it before it's too late?
