Deina is trapped. As one of the Soul Severers serving the god Hades on earth, her future is tied to the task of shepherding the dying from the mortal world—unless she can earn or steal enough to buy her way out. So when the tyrant ruler Orpheus offers both fortune and freedom to whoever can retrieve his dead wife, Eurydice, from the Underworld, Deina jumps at the chance. To succeed, however, she must enter an uneasy alliance with a group of fellow Severers that she neither likes nor trusts. As their perilous journey into the realm of Hades begins, with the reward of freedom ahead, what will it take for Deina to reach her prize? From the authors of A Throne of Swans and A Crown of Talons comes a stunning new YA duology set in a world inspired by the mythology of ancient Greece, perfect for fans of Alexandra Bracken’s Lore and Jessie Burton’s Medusa .","forthcoming":false,"isbn13":"9781536244533","publication_date":"20250909","publisher":"Candlewick Press","slug":"daughter-of-the-underworld","subtitle":"","title":"Daughter of the Underworld"},"discovery":{"categories":{"all":[{"bisac_code":"YAF030020","confidence_band":"medium","label":"Greek & Roman Myths for Teens","score":0.848,"source":"bisac_hint_model"},{"bisac_code":"YAF024020","confidence_band":"medium","label":"Historical YA - Ancient Worlds","score":0.8354,"source":"bisac_hint_model"},{"bisac_code":"YAF019030","confidence_band":"medium","label":"Epic YA Fantasy","score":0.8187,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"YAF030020","confidence_band":"medium","label":"Greek & Roman Myths for Teens","score":0.848,"source":"bisac_hint_model"},{"bisac_code":"YAF024020","confidence_band":"medium","label":"Historical YA - Ancient Worlds","score":0.8354,"source":"bisac_hint_model"},{"bisac_code":"YAF019030","confidence_band":"medium","label":"Epic YA Fantasy","score":0.8187,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"YAF019060","confidence_band":"high","label":"YA Fantasy Romance","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF024020","confidence_band":"high","label":"Historical YA - Ancient Worlds","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF030020","confidence_band":"high","label":"Greek & Roman Myths for Teens","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Greek & Roman Myths for Teens","score":0.848,"slug":"greek-roman-myths-for-teens"},{"label":"Historical YA - Ancient Worlds","score":0.8354,"slug":"historical-ya-ancient-worlds"},{"label":"Epic YA Fantasy","score":0.8187,"slug":"epic-ya-fantasy"}],"reader_fit":["Good for readers who enjoy Greek & Roman Myths for Teens","Good for readers interested in fantasy","Good for fans of Fantasy"],"related_lists":[{"intro":"Familiar myths and tales reworked with a new lens and voice.","slug":"how-its-told-retellings","title":"Retellings","url":"https://bookfrontier.com/lists/how-its-told-retellings"}],"series":null,"similar_books":[{"authors":["Bea Fitzgerald"],"book_id":"9781464243080","cover_image_url":"https://img.bookfrontier.com/9781464243080.jpg?v=20260417T162657Z%3A2026-04-17T16%3A26%3A57Z","score":13.9127,"title":"Girl, Goddess, Queen","url":"https://bookfrontier.com/books/9781464243080"},{"authors":["Sarah Underwood"],"book_id":"9780063234529","cover_image_url":"https://img.bookfrontier.com/9780063234529.jpg?v=20260417T162657Z%3A2026-04-17T16%3A26%3A57Z","score":13.7926,"title":"Gentlest of Wild Things","url":"https://bookfrontier.com/books/9780063234529"},{"authors":["Nikki Patel","Homer Todiwala","Donnabella Mortel","Vidish Athavale"],"book_id":"9780593479285","cover_image_url":"https://img.bookfrontier.com/9780593479285.jpg?v=20260417T162657Z%3A2026-04-17T16%3A26%3A57Z","score":13.7783,"title":"The Isles of the Gods","url":"https://bookfrontier.com/books/9780593479285"},{"authors":["Axie Oh"],"book_id":"9781250780867","cover_image_url":"https://img.bookfrontier.com/9781250780867.jpg?v=20260417T162657Z%3A2026-04-17T16%3A26%3A57Z","score":12.9552,"title":"The Girl Who Fell Beneath the Sea","url":"https://bookfrontier.com/books/9781250780867"},{"authors":["Claire Andrews","Claire M.
