Without words, he is able to take us back to the
Cambrian oceans for a glimpse of the lives of some astonishingly alien looking creatures. Josh's speculations about these animals' behavior are purely imaginative, but are based on our understanding of fossil evidence and the habits of similarly structured, existing arthropods. These ancient animals' interactions cause the cascading events that propel the story.

These creatures lived in a world where the oceans teamed with life, but the continents were devoid of plants or animals. All of the action of this time took place in the thriving seas. Josh ran his ideas by
Sam Gon III to test the plausibility of his hypotheses about the vanished world of the Cambrian ocean. His exploration of these fascinating ideas is certain to inspire readers. I'm sure that anyone with even a passing curiosity about trilobites and their contemporaries will savor every page of
this gorgeous book; I know I did. Thanks Josh!
