"I found it strikingly original and surprisingly riveting, and though the yuck factor is high, that's exactly what will draw children in to learn about both World War I and microbiology." Jane Sullivan, The Age/Sydney Morning Herald. "It's wonderful to see a book written for youth tackle the complex subject of viruses and the human microbiota in such an entertaining way. No bacteria is left unturned in this book, and the explanations in the Appendix about ideas, phrases and concepts covered in the story (there are numbered circles that appear throughout the story, and these correspond to the information in the Appendix) add to the understanding of the often complex processes and information presented. Highly recommended for anyone who wants to learn more about the human gut, microbiology, viruses, cross infection and WWI Western Front history."
