Through the eyes, ears, and tail of Lexi Catt, Marian Keen brings to life the wonderful story of the Curies, told in an engaging style for children. Keen skilfully weaves the difficulties experienced by women of the era into her story and shows how Marie and her daughters' dedication, skills, and knowledge helped them overcome these. Keen's telling of the work of Marie and the 'petites Curies' during World War I is remarkable in its emotive immediacy - the reader is carried along with them. Keen combines the history of war, the history of science, and the attitudes of the late 19th and early 20th centuries in a way that is understandable and attractive to children.
