“A simply profound exploration of time and timelessness."—Booklist, STARRED review
A marvelous picture book about the history of the world, told through the story of one small hill, from world renowned master storyteller Jairo Buitrago and Hans Christian Andersen Award shortlisted illustrator Linda Wolfsgruber.
Somewhere in this world there is a small hill, where three girls are taking off their shoes. But many thousands of years ago, a dinosaur saw a brilliant star falling as he stood on that same hill. The ice age comes and goes, castles are built and fall into ruin. The world grows and changes around the hill: trees are planted, a family seeks refuge, and houses are built below it. Now it’s time for the girls to put their shoes back on and go home.
This beautiful book provides us with a way to imagine the incredible things that happened in our world before we were around.
