Mrs. Mumford's Missing — Lucianne DeLong

Saloman Sawdust has brought young readers another fun-loving sticker book. Mrs. Mumford's Missing is the story of first grader's anxiety when they discover their teacher is not in her usual place -- her classroom. A search is launched high and low, front and back, in and out, up and down, over and under. Just when they think their efforts are useless, they discover she's really not missing at all.
