Heinecke, previously an author of science books for kids, draws on her art and science degrees in this vividly elucidating and enthralling double portrait which reads like a biographical novel rather than a dual biography as she boldly imagines the thoughts and feelings of her two magnetic subjects and invents dialogue. Some readers may object to these creative-nonfiction techniques, but extensive bibliographic notes attest to the factual foundation supporting this irresistible, dramatic, many-faceted, and, yes, illuminating tale of two extraordinary geniuses and their friendship. Heinecke’s fresh take on Curie is welcome, and her portrayal of the too-little-known Fuller is revelatory..
