A teen girl travels to an exclusive boarding school after a deadly incident at her old school, but the wood-paneled halls of Agathion are built over centuries of secrets—including an ancient society which may have ties to demonic magic—in this dark academia fantasy perfect for fans of Curious Tides . Page Whittaker has always been an outcast. And after the deadly incident that destroyed her single friendship at her old school, she needs a fresh start. Which is why when she receives a scholarship offer from Agathion College, an elite boarding school folded deep within the moors of Scotland, she doesn’t even consider turning it down. Agathion is everything Page has ever wanted: a safe haven full of dusty books, steaming cups of tea and rigorous intellectual debate. And for the first time in her life, Page has even managed to become part of a close group of friends. Cyrus, Ren, Gideon, Lacey and Oak help her feel at home in Agathion's halls--the only problem is, they're all keeping secrets from her. Page doesn't know it yet, but her perfect new school has dark roots--roots that stretch back to its crooked foundation, and an ancient clandestine society with rumored ties to demonic magic. Soon, Page will be forced to learn that not everyone at Agathion is who they say they are. Least of all, her friends. Agathion claims to teach its students history…but some histories should stay buried.","forthcoming":false,"isbn13":"9780593811016","publication_date":"20250218","publisher":"Random House Children's Books","slug":"unhallowed-halls","subtitle":"","title":"Unhallowed Halls"},"discovery":{"categories":{"all":[{"bisac_code":"YAF062040","confidence_band":"medium","label":"YA Supernatural Thrillers","score":0.8453,"source":"bisac_hint_model"},{"bisac_code":"YAF019020","confidence_band":"medium","label":"Dark YA Fantasy","score":0.8375,"source":"bisac_hint_model"},{"bisac_code":"YAF019050","confidence_band":"medium","label":"Wizards & Witches for Teens","score":0.8307,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"YAF062040","confidence_band":"medium","label":"YA Supernatural Thrillers","score":0.8453,"source":"bisac_hint_model"},{"bisac_code":"YAF019020","confidence_band":"medium","label":"Dark YA Fantasy","score":0.8375,"source":"bisac_hint_model"},{"bisac_code":"YAF019050","confidence_band":"medium","label":"Wizards & Witches for Teens","score":0.8307,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"YAF019020","confidence_band":"high","label":"Dark YA Fantasy","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF045000","confidence_band":"high","label":"Paranormal & Supernatural for Teens","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF054010","confidence_band":"high","label":"Boarding School YA","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"YA Supernatural Thrillers","score":0.8453,"slug":"ya-supernatural-thrillers"},{"label":"Dark YA Fantasy","score":0.8375,"slug":"dark-ya-fantasy"},{"label":"Wizards & Witches for Teens","score":0.8307,"slug":"wizards-witches-for-teens"}],"reader_fit":["Good for readers who enjoy YA Supernatural Thrillers","Good for readers interested in young","Good for fans of Fantasy"],"related_lists":[{"intro":"","slug":"shelf-yaf019050-wizards-witches","title":"Wizards & Witches Books","url":"https://bookfrontier.com/lists/shelf-yaf019050-wizards-witches"},{"intro":"Campus-set fiction where ambition, secrecy, and atmosphere do the heavy lifting.","slug":"how-its-told-dark-academia","title":"Dark Academia Books","url":"https://bookfrontier.com/lists/how-its-told-dark-academia"}],"series":null,"similar_books":[{"authors":["Hanna Alkaf","Margaret Owen"],"book_id":"9780593427453","cover_image_url":"https://img.bookfrontier.com/9780593427453.jpg?v=20260417T232332Z%3A2026-04-17T23%3A23%3A32Z","score":19.4644,"title":"The Grimoire of Grave Fates","url":"https://bookfrontier.com/books/9780593427453"},{"authors":["Erin A.
