Winner of the 1972 Newbery Medal, this wonderful fantasy by Robert O'Brien has stood the test of time and is a great read. Mrs. Frisby is a widowed mouse with four small children. The family must move to their summer quarters immediately or face almost certain death. But Mrs. Frisby's 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. Recommended for ages 8 - 12.
