Some extraordinary rats come to the aid of a mouse family in this Newbery Medal Award-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...

When mouse widow Mrs. Frisby needs advice on how to move her children safely, she consults the rats who live under the rosebush. Not only do they help her, they tell her of their escape from a laboratory where experimentation had made them literate, and of the brave death of her husband.
