Seven-year-old Violet Mackerel has a new theory: If someone has a problem and you give them something small, like a feather, or a pebble, or a purple lozenge, that small thing might have a strange and special way of helping them.

Violet gets the chance to put "The Theory of Giving Small Things" to the test when a bad case of tonsillitis requires the removal of her tonsils, and she suspects that the purple lozenge from Doctor Singh may help her in quite an extraordinary way. And indeed, with a freezer stocked with breakfast ice cream, a wonderful new friend in the waiting room, and the certainty that surgery will transform her voice into that of an opera singer on the radio, Violet's recovery proves more than extraordinary--it is, unquestionably, remarkable.
