ANDREW CLEMENTS (1949-2019) was a New York Times bestselling author whose beloved modern classic Frindle has sold over six million copies, won nineteen state awards (and been nominated for thirty-eight!), and been translated into over a dozen languages. Before writing Frindle, Andrew worked as a public school teacher outside Chicago. Called the "master of school stories" by Kirkus Reviews, Andrew wrote over eighty acclaimed books for kids, including, most recently, The Friendship War and The Losers Club, which School Library Journal called "engaging and funny . . . a laugh-out-loud first purchase" in a starred review.
