Jane Smiley's TWENTY YAWNS is enough to put you to sleep.
(Not a problem, since that’s the purpose of this beautiful picturebook.)
In this story, a family at the beach heads for their home/cabin, tired after a full and active day. Soon everyone’s overcome by yawns.
A great bedtime read-aloud book, beautifully illustrated by Laren Castillo... and a possibility for The Grandfather List.
