Avi is part of a family of writers extending back into the nineteenth century. Born in 1937 and raised in New York City, Avi was educated in local schools before going to the Midwest and then back to NYC to complete his education. He started out as a playwright while working for many years as a librarian. He began writing books for young people when the first of his kids came along.
His first book was published in 1970. Since then he has published more than seventy books and won many awards, including the Newbery Medal, two Newbery Honors, two Boston Globe–Horn Book Awards, a Scott O’Dell Award for Historical Fiction, and many children’s choice awards. Avi frequently travels to schools around the country to talk to his readers.
Among his most popular books are Crispin: The Cross of Lead, The True Confessions of Charlotte Doyle, Nothing But the Truth, the Poppy books, Midnight Magic, and The Fighting Ground. His other books with Candlewick Press include What Do Fish Have to Do with Anything? and The Most Important Thing: Stories About Sons, Fathers, and Grandfathers. Avi lives in Clark, Colorado, with his wife.
