Query: amazingly imaginative journey through the micro-cosmos

Meg's little genius brother, Charles Wallace, is having trouble fitting into first grade, and Meg is having trouble letting him grown into his own. She's also having trouble with Mr. Jenkins, her little brother's principal, who seems to have two evil twins. Meanwhile, Charles Wallace is turning more and more sickly. Meg, in a journey through the macro and micro cosmos, must discover her purpose as well as sort out her emotions and feelings. L'Engle's genius series deals with a brand new form of mythology, that of quantum physics. It's beautiful and wondrous. Grade: A
