For Enola, longing for her absent mother and on the run from her older brothers, it is a fundamental fact of life that her name backwards spells alone. Her lonely London days include very few people except her landlady, Mrs. Tupper. Although nearly deaf and a truly dreadful cook, the elderly Mrs. Tupper is endearing—really the closest thing Enola has to family these days. So imagine her horror when she comes home to find Mrs. Tupper kidnapped! Who would have taken her, and why? And what does Florence Nightingale have to do with it? Is there more to the kind, homely Mrs. Tupper than meets the eye? No matter what the risk, Enola will not rest until dear Mrs. Tupper is safe at home. And whoever took her had better watch out—because this time, it's personal. From the master of mystery Nancy Springer, here's another absorbing adventure for our award-winning, critically acclaimed, unstoppable young heroine.
