Wendy Lichtman writes personal essays for the Washington Post, New York Times, San Francisco Chronicle, and Good Housekeeping, among other national publications. She holds a degree in mathematics and has tutored public-school students in algebra for the past several years. When she decided to write about a teen realizing that some questions have more than one right answer, algebra, with its unknowns and variables, seemed a perfect metaphor. Wendy Lichtman lives in Berkeley, California. (from the publisher's website)"
