Gwenyth Reitz was born in Sri Lanka, and has since lived and worked in California, Washington, Alaska, Montana, Japan, and Mongolia. When not intrepidly exploring she writes genre-blending YA stories with swoony romance, mystery, humor, and heart. Gwenyth now lives in NYC with her husband and two kids, where she can often be found scribbling late into the night on her rooftop like the caffeine-obsessed night-owl she is. 

As a theater maker with an MFA in Interdisciplinary Art, Gwenyth works for Lincoln Center Theater teaching acting and directing teens. For fun, she likes to sing Hamilton karaoke, maybe not well, but with gusto. Her YA supernatural romcom, You’re Dead to Me, Reed Walker, debuted with Macmillan’s Roaring Brook Press in 2026. Her second YA title, Prom Anomaly, will follow in 2028.
