Eleanor Glewwe was born in Washington, D.C. and grew up in Maryland and Minnesota, with a brief interlude in Paris. Her parents sent her to French immersion school in kindergarten, and she began studying Mandarin in high school. At various points in her life, she has also attempted to teach herself Cantonese, German, Spanish, Hindi, Ancient Greek, and Turkish. She plays the cello and used to host music parties for her friends, arranging Renaissance dances and Baroque concerti grossi for unorthodox instrumentation. She attended Swarthmore College, where she majored in Linguistics and Languages and worked in the music library. After graduating, she spent a year at an interfaith advocacy organization, working for social justice at the Minnesota legislature. In addition to being a writer, Eleanor is a folk dancer and a Sacred Harp singer. She currently lives in Los Angeles, where she is a graduate student in linguistics. Her debut novel SPARKERS, a middle grade fantasy, was published by Viking in 2014, and its companion WILDINGS came out in November 2016.
