Going on to sell over a million books and with numerous best sellers on the shelves, she has amassed a loyal fanbase, but her love for writing doesn’t end at her own. Ashley was inducted to the Writer’s Guild of America in 2017 and began developing television series for Warner Horizon and Universal in 2015. With a keen eye for what makes a good story, Ashley is a lover of both fiction and non-fiction works.
