A cautionary tale about the consequences of that most contagious of conditions: yawning. An omniscient narrator warns readers about the perils of yawning (yawns can lead to bedtime), so cautions against listening to lullabies or bedtime stories, or catching others in the process of yawning.

But even a book about not yawning is likely to lead to the inevitable...

The lists of perils and tonics are comically portrayed with the deceptively childlike drawings of Serge Bloch.

A droll and infectious confection.
