FROM SARAH:

Who knew Marie Curie had a sister? Not me! But she did, and she was important to the success of Marie herself. A delightful picture book.

FROM THE PUBLISHER:

Marie Curie has long been a well-known name around the world. Though Marie made extraordinary scientific advances discovering new elements with her husband, Pierre, many students do not know about the powerful bond that propelled her into science: her sisterhood with Bronia! A force in academia and health care herself, Bronia made significant contributions to the scientific world, along with her loving support of sister Marie.
