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 daughters, 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 debut novel, YOU’RE DEAD TO ME, REED WALKER, comes out in the Spring of 2026 with Macmillan’s Roaring Brook Press, followed by an untitled second novel in 2027. Gwenyth is represented by Dr. Uwe Stender of Triada US Literary Agency. You can find her on socials @GwenythReitz
