Sarah Flannery is an Irish teenager who won the Irish and European Young Scientist of the Year awards. In friendly, conversational prose, she tells how she moved from simple math puzzles played during dinnertime discussions to number theory, the work of Eratosthenes, cryptography, and discoveries of her own. Her mathematician father co-wrote In Code and it was through his puzzle-solving approach that Sarah found herself challenged to continue an adventure in math.
