Ers iddi fod yn ferch fach roedd Rebecca wrth ei bodd yn dweud straeon, ac o fod yn ifanc iawn gwyddai mai ysgrifennu nofelau oedd hi am wneud. Ers graddio o Brifysgol Bangor gyda gradd Saesneg ac Ysgrifennu Creadigol mae Rebecca wedi gweithio fel athrawes, swyddog datblygu, gweinydd dyneiddiol a chyfieithydd. Mae hi'n byw Mhrestatyn, gyda’i gŵr a phlant. Enillodd #Helynt, ei nofel gyntaf i oedolion ifanc, Wobr Tir na n-Og 2021 a Llyfr y Flwyddyn Plant a Phobl Ifanc 2021.


​From a very young age Rebecca knew that she wanted to be a novelist. Since graduating from Bangor University with a BA(hons) in English and Creative Writing Rebecca has worked as a teacher, Welsh development officer, humanist celebrant and translator. She lives in Prestatyn, with her husband and children. Her first YA novel, #Helynt, won a 2021 Tir na n-Og Award and the 2021 Book of the Year (Children and Young People Category).
