Kiersten White
Kiersten White’s storytelling is a blend of fierce imagination, sharp wit, and deep emotional resonance. Known for her ability to spin complex tales of fantasy, horror, and the supernatural, White has captured the hearts of readers with her distinctly bold, often dark narratives. Her stories are where the boundary between the ordinary and the extraordinary blurs, where readers are invited to dive into worlds filled with magic, monsters, and unforgettable heroines.
Born in Salt Lake City, Utah, Kiersten grew up with a passion for both reading and writing, though she was the kind of person who loved to daydream about new worlds before ever setting them down on paper. From an early age, she found herself enchanted by stories that pushed the limits of what was possible—stories that felt real, even when they were anything but. That love of the fantastical is something that continues to infuse her books, drawing from her own love of adventurous narratives and her curiosity about what lies beneath the surface of reality.
