"In the wake of the COVID-19 pandemic, many publishers have seen an opportunity to reissue previously published books on viruses and pandemics. As a reader, it is always difficult to know whether you are actually getting any updated content beyond the obligatory new preface or afterword, or whether this is just a quick cash-grab. Fortunately, the third edition of Zimmer's famous virology primer A Planet of Viruses is here to prove those suspicions wrong. Each essay has been updated with new research published in the last six years. It would have been easy to just slap in the COVID-19 essay, send it off to the printers, and call it a third edition. This is not the case, however, which reflects very well on both the author and the publisher. Furthermore, this edition features stylish woodcut-like illustrations from Ian Schoenherr that open each chapter. A Planet of Viruses is a captivating primer to the world of viruses that requires zero background in biology.

The brevity of the essays and the small size of this book make it a suitable first introduction to this fascinating part of our world. Even for a biologist such as myself, there is much to admire in Zimmer's writing: these essays are miniature masterclasses in science communication. If, for some reason, you have so far missed out on this book then what are you waiting for? At this price and this size, you have no excuse not to indulge.".
