Author bio
Claudia Mills was born in New York City in 1954, and she grew up in a home where books and writing felt like part of everyday life. Her mother was an elementary school teacher who loved to write, and that mattered a lot. So did Mills's younger sister, who shared her appetite for reading and for making up whole imaginary worlds together.
When she was six, her mother gave her a blank notebook and told her it would be her poetry book.
That small gift seems to have set the tone for everything that came after. As a child, Mills wrote poems, stories, and plays, and by the time she was older she was already filling pages with the kind of earnest, serious work kids write when they feel everything deeply. She has said that she even wrote a hundred-page autobiography about one year of her own life. That mix of intensity, humor, and close attention to ordinary childhood feelings would later become one of the signatures of her fiction.
Her academic path was just as bookish. Mills earned her bachelor's degree from Wellesley College, then went on to Princeton for a master's degree and, later, a Ph.D. in philosophy. She also earned a library science degree from the University of Maryland, with a focus on children's literature. That combination makes a lot of sense once you read her work. Her stories are never preachy, but they are full of kids thinking hard about fairness, loyalty, family, embarrassment, kindness, and what it means to do the right thing.
Before she became widely known as an author, she worked in children's publishing at Four Winds Press and later worked as an editor in public policy. Her first published novel, At the Back of the Woods, grew out of those early years of learning how stories get made and remade. She went on to build a long writing career while also teaching philosophy, first in Maryland and then for many years at the University of Colorado Boulder, where she later became associate professor emerita.
That double life, storyteller and philosopher, suits her.
Mills has written across chapter books, middle grade novels, picture books, and scholarly work, but many readers know her best for school stories that take children's problems seriously without ever making them heavy-handed. In Kelsey Green, Reading Queen, Annika Riz, Math Whiz, and the other Franklin School Friends books, she turns third-grade worries into lively, funny drama. In How Oliver Olson Changed the World, a boy with overprotective parents tries to claim a little independence. In Zero Tolerance, a middle schooler is punished for accidentally bringing a paring knife to school, and the story opens into a thoughtful look at rules and justice. In Write This Down, an ambitious young writer learns that publishing the truth can hurt people she loves. And in The Lost Language, friendship, family strain, and a near-extinct language come together in a tender verse novel.
She is especially good at writing children who are smart, earnest, funny, and a little worried.
Her books often center on classrooms, siblings, best friends, and kids with strong interests, reading, math, animals, writing, science, theater, history. She has also written about grief, adoption, disability, mental illness, and moral choice, always in plain, approachable language. Awards have followed, including a Colorado Book Award for The Totally Made-up Civil War Diary of Amanda MacLeish and the Maryland Blue Crab Young Reader Award for How Oliver Olson Changed the World.
Mills has long lived in Boulder, Colorado, and she has written about working early in the morning while the house is quiet, often with tea or hot chocolate nearby and the Rockies outside the window. She is the mother of two sons and a grandmother as well. Later in her career, she also taught in children's literature programs at Hollins University. Even with a large body of work behind her, her books still feel close to the real lives of kids, which is a big part of why they last.
