Hopkinson, Deborah. Evidence!: How Dr. John Snow Solved the Mystery of Cholera. New York: Alfred A. Knopf, 2024.
In 1854, cholera struck London, England. People were dying and everyone thought it was caused by something in the air they breathed. John Snow, a doctor, thought otherwise and proved it. The source of the problem was contaminated well water. Accompanied by a lengthy afterword, this informative picture book is useful both as a read-aloud for younger children and a fascinating independent reading book for older students.Â
The author has written many books: novels and picture books, fiction and non-fiction. Generally, they are well-designed with the format not distracting from the story. Unfortunately, this one is slightly marred by the font; it is too small the match the style of a picture book and too formal to match the mood of the illustrations. Nevertheless, the book is highly recommended for readers ten years old and up.
