The Revenge of the Substitute Teacher — Jan Lawrence

You'll never forget this substitute!

All summer long, Jeff and Matt have waited to hear who their fifth-grade teacher will be. Then the letter arrives: Mr. Manlin, Room 512. Oh, no! Not Mr. Manlin! Anyone but Mr. Manlin! Everyone knows that he's the strictest, meanest teacher in the whole school.

But when Mr. Manlin suddenly disappears and is replaced by a string of unsuspecting substitute teachers, Jeff and his friends can't believe their luck. Until Ms. Wilder shows up, that is! She makes class with Mr. Manlin look like a day at the beach!
