Girlcrush by Florence Given

"Girlcrush is a dark feminist retelling of Jekyll & Hyde by bestselling author Florence Given. In Given's debut novel, we follow Eartha on a wild, weird and seductive modern-day exploration as she commences life as an openly bisexual woman whilst also becoming a viral sensation on Wonderland, a social media app where people project their dream selves online. The distance between her online and offline self grows further and further apart until something dark happens that leads her into total self-destruction, forcing Eartha to make a choice; which version of herself should she kill off?"
