A. D. RHINE is the pseudonym of Ashlee Cowles and Danielle Stinson. The authors are united by their military “brat” upbringing, childhood friendship spanning two decades, and love of classical literature. Ashlee holds graduate degrees in Medieval History from the University of St. Andrews and Theological Studies (with an emphasis in the Ethics of War and Peace) from Duke University. Danielle holds a Master of Arts in Law and Diplomacy from Tufts University. Their adult debut Horses of Fire (releasing from Dutton in 2023) is the book they have always dreamt of writing together.
