A field mouse named Mrs. Brisby enlists the aid of a race of intelligent rats to save her home and her sick child.

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 renders them a great service.

‘Racso, a brash and boastful little rodent, is making his way to Thorn Valley, determined to learn how to read and write and become a hero. His bragging and lies get him off to a bad start, but a crisis gives him the opportunity to prove his mettle. A worthy successor [to Mrs. Frisby and the Rats of NIMH, a Newbery Medal winner by the author's father].'

Deep beneath a modern metropolis lies the Catacombs, a kingdom of remarkable rats of superior intellect . . . Juniper and his maverick band of rebel rats have been plotting ever since the Bloody Coup turned the Catacombs, a once-peaceful democracy, into a brutal dictatorship ruled by decadent High Minister Killdeer and his vicious henchman, Billycan, a former lab rat with a fondness for butchery. When three young orphan rats—brothers Vincent and Victor and a clever female named Clover—flee the Catacombs in mortal peril and join forces with the rebels, it proves to be the spark that ignites the long-awaited battle to overthrow their oppressors and create a new city: Nightshade City. This digital edition now includes the first chapter of The White Assassin, the second book in the Nightshade Chronicles.

On a mission of mercy, Mrs. Brisby stops to help a crow in trouble, only to suffer interminable delay and great personal danger.
