A. S. RAITHE is a fantasy author living near Pittsburgh with their spouse and children. A lifelong creative, Raithe discovered a passion for writing in high school after being introduced to a local bestselling author who was running a writers circle out of an independent bookstore. They went on to work as a freelance ghostwriter before stepping away from writing to return to college, until their spouse convinced them to get back to it for themself.

In 2022, Raithe met another author at a local convention who offered them a monthly serial in his magazine. Their dark fantasy serial, THE CURSE OF THE EBON MAW, debuted in August 2023, and Raithe was named Author of the Month in December of that year for their work on the series.

Their debut novel, THE ORIGAMI EARTH: TÍR NA NÓG, a young adult sapphic portal fantasy (intended for ages 16+), was released on June 1, 2026. Their next novel, THE SECRET OF HIDDEN CREEK, an upper middle-grade coming-of-age story in the tradition of a boy and his dog, but with a supernatural twist (intended for ages 10+), is currently scheduled for release on September 1, 2026.

Outside of writing, Raithe enjoys exercise, baking, gardening, folklore, and, key to their inspiration and creative process, hiking and music.
