Set on a family-run interstellar freighter called the Harland and a mysterious remote space station, E. K. Johnston's latest is story of survival and self-determination. Pendt Harland's family sees her as a waste of food on their long-haul space cruiser when her genes reveal an undesirable mutation. But if she plays her cards right she might have a chance to do much more than survive. During a space-station layover, Pendt escapes and forms a lucky bond with the Brannick twins, the teenage heirs of the powerful family that owns the station. Against all odds, the trio hatches a long-shot scheme to take over the station and thwart the destinies they never wished for.","forthcoming":false,"isbn13":"9780735231856","publication_date":"20210525","publisher":"Penguin Young Readers Group","slug":"aetherbound","subtitle":"","title":"Aetherbound"},"discovery":{"categories":{"all":[{"bisac_code":"YAF056020","confidence_band":"high","label":"Space Opera for Teens","score":0.8675,"source":"bisac_hint_model"},{"bisac_code":"YAF056010","confidence_band":"medium","label":"Alien Contact for Teens","score":0.8349,"source":"bisac_hint_model"},{"bisac_code":"YAF001010","confidence_band":"medium","label":"YA Pirate Adventures","score":0.8168,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"YAF056020","confidence_band":"high","label":"Space Opera for Teens","score":0.8675,"source":"bisac_hint_model"},{"bisac_code":"YAF056010","confidence_band":"medium","label":"Alien Contact for Teens","score":0.8349,"source":"bisac_hint_model"},{"bisac_code":"YAF001010","confidence_band":"medium","label":"YA Pirate Adventures","score":0.8168,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"YAF018000","confidence_band":"high","label":"YA Family Stories","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF031000","confidence_band":"high","label":"YA LGBTQ+","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF056020","confidence_band":"high","label":"Space Opera for Teens","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Space Opera for Teens","score":0.8675,"slug":"space-opera-for-teens"},{"label":"Alien Contact for Teens","score":0.8349,"slug":"alien-contact-for-teens"},{"label":"YA Pirate Adventures","score":0.8168,"slug":"ya-pirate-adventures"}],"reader_fit":["Good for readers who enjoy Space Opera for Teens","Good for readers interested in science","Good for fans of Science Fiction"],"related_lists":[{"intro":"Big-canvas speculative stories where first contact drives the stakes.","slug":"between-the-shelves-space-opera-alien-contact","title":"Space Opera and Alien Contact Books","url":"https://bookfrontier.com/lists/between-the-shelves-space-opera-alien-contact"}],"series":null,"similar_books":[{"authors":["Matthew J.
