Beginning with the mutations and evolution that brought life to Earth, this picture book soon focuses on snails as they climb out of the water and onto land. Mutations continued to happen, including to one specific snail who was discovered by a retired scientist. It was a smaller snail than normal, with a darker shell and a tentacle that had trouble unspooling, and a shell that spiraled in the opposite direction than other snails’. The scientist sent the unique snail to a snail laboratory where it was named Jeremy. It turned out that Jeremy’s body was a mirror image of most other snail’s and he also had inverted internal organs. Because of that, Jeremy could only mate with another mirror image snail, another one in a million. So the snail laboratory made a plea for the entire world to look for another “lefty” snail. Amazingly, in only a few weeks, two potential mates were found and sent to the snail laboratory. When eventually Jeremy had offspring, he was so old that he didn’t live to see them arrive. Sadly, none of the new snails had a left-spiraling shell. The mutation was once again dormant, but it will return again.
Inspired by a true story, this picture book is a touching mix of poetic description and scientific facts. Popova’s language embraces the reader, showing them the beauty and wonder in mutation, genetics and evolution. She marvels at finding two potential mates in the world for Jeremy and then delicately celebrates Jeremy’s life at the end. She writes with real intention both to reveal the amazing nature around us but also to describe the science, including Jeremy’s mirror image body, the way that snails mate, and the work of the scientists who cared enough to explore his mutation.
Zhu’s illustrations are awash in colors, from the blues of the original waters of life to the rich green of English gardens. Done in watercolor swirls and drips, the illustrations are a mix of close ups from a snail’s view and the bustle of humans transporting Jeremy and the other snails. There is even a lovely foldout page that invites readers to even more fully enter the depths of the garden.
Full of wonder and science. Appropriate for ages 5-7.
