Owlkids. Sept. 2022. 32p. Tr $18.95. ISBN 9781771474450.
PreS-Gr 2–This book squeezes millions of years of our past into a beautiful brief narrative of our last universal common ancestor, or LUCA. In brilliant, painterly illustrations, Lo invites young readers to trace a universal family tree, back before humans, before dinosaurs, when just a single cell found a way to start a world. Krossing’s text is nestled into the illustrations, pulling readers into the story, into the page, into the membrane of this ancestor. A short write up in the end pages provides greater LUCA context for readers searching for more, as well as a brief glossary of words that appeared in the story and a list of sources.
VERDICT In accessible and engaging illustrations, young readers will get excited about a tiny bubble and find plenty of fodder for story time discussion.
