Author bio
R L LaFevers was born in Los Angeles and grew up there with seven brothers, a lot of old books, and an ever-changing run of rescued animals. That noisy mix of stories, siblings, and pets shows up all through her work.
She knew early that she wanted to write. Reading the Narnia books as a child gave her the first real push.
Publication took time. After setting writing aside for a while, she came back to it when she was home with her two young sons and wanted something that was just for her. She spent years taking classes, going to workshops, and learning by doing before an agent finally offered representation and her first book sold.
Her early novels already show the things she likes best. The Falconmaster gives an outcast boy in Norman England a pair of rescued falcons, a hidden grandfather, and a brush with old forest magic. The Lowthar's Blade books turn classic quest fantasy into something lean and fast, with a blacksmith's son, an evil lord, and uneasy alliances between humans, goblins, and the Fey.
Those early books were shaped in part by the reading lives of her sons. She has said she wanted action, adventure, and fantasy for kids who were ready for big stories but not always ready for very long books. That practical instinct helps explain why the early R L LaFevers titles move so cleanly and so fast.
She writes middle grade as R L LaFevers and YA fantasy as Robin LaFevers.
Then came Theodosia and the Serpents of Chaos, one of the books that brought her to a wider audience. Theodosia, an eleven-year-old girl in Edwardian London, can see curses clinging to Egyptian artifacts in her parents' museum, and that setup lets LaFevers mix spooky adventure, dry humor, and a real love of research. Later, with The Flight of the Phoenix and the Nathaniel Fludd, Beastologist books, she brought the same curiosity to younger readers through brisk, globe-trotting adventures with mythical creatures.
Animals never really leave her stories.
You can feel that in the falcons of The Falconmaster, the creatures of the Nathaniel Fludd books, and even in the way her novels treat the natural world as old, strange, and worth paying attention to. Research matters too. She has spoken about digging through maps, folklore, history, and odd reference books until the next plot turn reveals itself. Her fiction often lives where history rubs up against myth, and where a child or teen notices the dangerous thing the adults have missed.
Her YA breakthrough was Grave Mercy, followed by Dark Triumph and Mortal Heart, the books of the His Fair Assassin trilogy. Set in fifteenth-century Brittany, they follow young women trained in a convent that serves the god of Death. Readers often come for the assassin nuns, but stay for the court politics, the moral mess, and the way each heroine has to decide what power is for. She later returned to that world in Courting Darkness and Igniting Darkness. By then she had become a New York Times bestselling author, but the appeal of her books stayed much the same: sharp young people under pressure, history with magic leaking through it, and hard choices that cannot be dodged.
She has described herself as an early-morning writer, happiest working while the house is still quiet and the subconscious feels close. It is a fitting routine for a novelist whose stories are always looking for the hidden world just under the ordinary one.
