In the Market of Zakrobat by Ori Elon is a cute picture book with a wonderful message. This book is a retelling of a Jewish folktale based on Yosef Moker Shabbos who always honors Shabbat, the Jewish day of rest. I would recommend this book for early readers as the vocabulary is simple, and they might be able to read this freely on their own or with a little assistance. The story is easy to understand, even for non-Jewish readers who may not be aware of Jewish customs and rituals.
