Life on the streets of the teeming city of Chennai is harsh for girls considered outcasts, but the sisters manage to find shelter on an abandoned bridge. There they befriend Muthi and Arul, two boys in a similar predicament, and the four children bond together and form a family of sorts. Viji starts working with the boys scavenging in trash heaps while Rukku makes bead necklaces, and they buy food with what little money they earn. They are often hungry and scared but they have each other--and Kutti, the best dog ever. When the kids are forced from their safe haven on the bridge, they take shelter in a graveyard. But it is now the rainy season and they are plagued by mosquitos, and Rukku and Muthu fall ill. As their symptoms worsen, Viji and Arul must decide whether to risk going for help--when most adults in their lives have proven themselves untrustworthy--or to continue holding on to their fragile, hard-fought freedom.

    (And you, dear reader, can test your wits right alongside them.) But in the end just four very special children will succeed.

But with their newfound friendship at stake, will they be able to pass the most important test of all?This tenth anniversary edition of The Mysterious Benedict Society includes over thirty pages of bonus materials that will delight old and new fans alike.
