Somehow, between starring alongside Rihanna in a huge sci-fi movie, shaving her head, and traveling to Uganda with Girl Up and the United Nations, Cara Delevingne also found time this year to write a novel. And you'll be able to read the model-actress-humanitarian-style star's first book quite soon.

In an Instagram post on Tuesday, Cara revealed the cover art and release date for the novel. "I am so excited to share the cover for my first novel MIRROR, MIRROR coming out 5th October. It's a story about friendship, identity and the fact that appearances can be deceiving. I'm in love with the characters Red, Naomi, Leo and Rose who are feisty and vulnerable in equal measure and I can't wait for you to meet them," she captioned an animated video of her book's intriguing cover. Cara also noted that Mirror, Mirror is already available for preorder on the HarperCollins's website.

The 25-year-old first announced that she was working on a book in March, when she posted a photo on Instagram of her posing with the Mirror, Mirror manuscript. "Another pinch me moment!! Announcing my first novel Mirror, Mirror, coming out this October! ....I love these characters so much, I love what they stand for, what this story represents. The process of putting this novel together has been life changing and something I hold really close to my heart!!" she wrote at the time.

According to HarperCollins, the book revolves around a group of "misfits" as they try to figure out why a friend mysteriously vanished and then reappeared in a coma. "To understand what happened to Naomi, Red, Leo and Rose must ultimately face their own dark secrets and fears, and reconcile the difference between what they feel inside and what they show to the world," the description says. "Cara Delevingne reveals another facet of her amazing talent with this powerful novel about identity, sexuality, gender, emotional pain, the complicated world of social media, and the dangerous weight of appearances that are not what they seem."

Cara is well-versed in the topics she covers in her book: She's been refreshingly vocal about her own sexual fluidity and recently spoke to Glamour about the response she's received since coming out as sexually fluid. "Someone is in a relationship with a girl one minute, or a boy is in a relationship with a boy, I don't want them to be pigeonholed...I am very happy how sexuality has become easier and freer to talk about, especially for kids." And earlier this summer, shortly after shaving her head for an upcoming film, Cara opened up on Instagram about her belief that beauty should be more broadly defined than it currently is in society. "The more we embrace who we are as people and rely less on our physical attributes, the more empowered we become. Beauty shouldn't be so easily defined. It is limitless," she wrote. "Its exhausting to be told what beauty should look like."
