photorealistic art for a book cover, featuring a determined and intelligent 16-year-old girl with dark brown hair and bright blue eyes. She should be standing in front of an elite, ivy-covered boarding school with gothic architectural style. The background should include elements of secrecy and intrigue, such as shadows or hidden figures, to evoke a sense of mystery. The color palette should be dark and moody, with contrasting light to highlight the protagonist. Ensure the image is vertical, with a 3:4 ratio, and right side up. No text should be included on the cover. --aspect 3:4
