This bold, sizzling YA novel reimagines the Once and Future King as a teenage girl determined to save the universe from an evil curse. My name is Ari Helix. I have a magic sword, a cranky wizard, and a revolution to start. I've been chased my whole life. As a fugitive refugee in the territory controlled by the tyrannical Mercer corporation, I've always had to hide who I am. Until I found Excalibur. Now I'm done hiding. When Ari crash-lands on Old Earth and pulls a magic sword from its ancient resting place, she is revealed to be the newest reincarnation of King Arthur. Then she meets Merlin, who has aged backward over the centuries into a teenager, and together they must break the curse that keeps Arthur coming back. Their quest? Defeat the cruel, oppressive government and bring peace and equality to all humankind. No pressure. * \"All hail this worthier-than-ever, fresh, and affirming reincarnation of the legendary king and her round table of knights which dazzles with heroic flair, humor, and suspense.\" — Kirkus , starred review","forthcoming":false,"isbn13":"9780316449274","publication_date":"20190326","publisher":"Little, Brown and Company","slug":"once-amp-future","subtitle":"","title":"Once & Future"},"discovery":{"categories":{"all":[{"bisac_code":"YAF030010","confidence_band":"medium","label":"Arthurian YA","score":0.8451,"source":"bisac_hint_model"},{"bisac_code":"YAF019040","confidence_band":"medium","label":"Historical YA Fantasy","score":0.8159,"source":"bisac_hint_model"},{"bisac_code":"YAF019030","confidence_band":"medium","label":"Epic YA Fantasy","score":0.814,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"YAF030010","confidence_band":"medium","label":"Arthurian YA","score":0.8451,"source":"bisac_hint_model"},{"bisac_code":"YAF019040","confidence_band":"medium","label":"Historical YA Fantasy","score":0.8159,"source":"bisac_hint_model"},{"bisac_code":"YAF019030","confidence_band":"medium","label":"Epic YA Fantasy","score":0.814,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"YAF001020","confidence_band":"high","label":"YA Survival Stories","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF003000","confidence_band":"high","label":"YA Apocalyptic Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF030010","confidence_band":"high","label":"Arthurian YA","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF052040","confidence_band":"high","label":"YA Romance - LGBTQ+","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Arthurian YA","score":0.8451,"slug":"arthurian-ya"},{"label":"Historical YA Fantasy","score":0.8159,"slug":"historical-ya-fantasy"},{"label":"Epic YA Fantasy","score":0.814,"slug":"epic-ya-fantasy"}],"reader_fit":["Good for readers who enjoy Arthurian YA","Good for readers interested in space","Good for fans of Fantasy"],"related_lists":[],"series":null,"similar_books":[{"authors":["Cory McCarthy","A.
