“Thoroughly engrossing, thought-provoking fantasy.” — School Library Journal (starred review) Some extraordinary rats come to the aid of a mouse family in this “treasure of a book” ( The Times , London), the Newbery Medal–winning classic by notable children’s author Robert C. O’Brien. Mrs.

Frisby, a widowed mouse with four small children, is faced with a terrible problem. She must move her family to their summer quarters immediately, or face almost certain death. But her youngest son, Timothy, lies ill with pneumonia and must not be moved.

Fortunately, she encounters the rats of NIMH, an extraordinary breed of highly intelligent creatures, who come up with a brilliant solution to her dilemma. And Mrs. Frisby in turn renders them a great service.
