Reviews

**STARRED REVIEW**
"Buzzeo's considerable storytelling skills zero in on fascinating details, such as the experience of unearthing fossils, while Sudyka's entrancing illustrations reflect this attention to detail and the passion Sue brought to her work. Additionally, it's refreshing to see a profile of a modern, female scientist, who is respected in her field."-- "Booklist"
