Anne Mazer grew up in a family of writers in upstate New York. Intending to be an artist, she enrolled in Syracuse University's College of Visual and Performing Arts before moving to Paris, where she would live for three years, studying French language and literature and beginning to write.
Mazer is the author of forty-four books for children and adults. Her seven novels include The Salamander Room, a Reading Rainbow feature selection and a 1993 ABC Children's Choice; Moose Street, a Booklist Editors' Choice for best book of 1992; and The Oxboy, an ALA Notable Book and a 1993 Notable Children's Trade Book in the Field of Social Studies. Mazer's short stories have been included in a number of collections, and she has published her own book of short stories, A Sliver of Glass. She is also the editor of several anthologies that are widely used in classrooms from the elementary through the college level.
Mazer's many books for young readers include the bestselling Amazing Days of Abby Hayes series, which has extended over eleven years and twenty-two books, and the Sister Magic series. Her latest work, coauthored with Ellen Potter, is Spilling Ink: A Young Writer's Handbook, which was a CLA Notable Children's Book in the Language Arts in 2011 and a 2010 Cybils Award finalist.
