I'm Stephanie, a proud biracial Mexican-American from San Diego with over ten years of experience in the publishing industry. I've read the slush pile for literary agents, edited books for small publishing presses, and collaborated with numerous self-published and agented writers to build their craft and polish their manuscripts. In addition to being a freelance book editor, I write my own YA novels in my spare time--some of which have been published. Basically, it's all books all the time in my world, and I couldn't be happier. Besides books, I love traveling, hiking, swimming, and adventuring in the outdoors. I majored in film production at San Diego State University, and continue to enjoy watching quirky TV shows and cinematic films in my free time. I also play guitar and sing in a community choir. Sometimes I share my music on Instagram, so keep an eye out!
