Deep-space exploration is a reality and teleportation is routine. But this time something seems to have gone very, very wrong. Seventeen-year-old Jessica Mathers wakes up in a lander that’s crashed onto the surface of Carver 1061c, a desolate, post-extinction planet fourteen light-years from Earth. The planet she was supposed to be viewing from a ship orbiting far above. The corridors of the empty lander are covered in bloodyhand prints; the machines are silent and dark. And outside, in the alien dirt, there are fresh graves carefully marked with names she doesn’t recognize. Now Jessica must unravel the mystery of the destruction all around her—and the questionable intentions of a familiar stranger. Self-determination and survival collide in this haunting, pulse-pounding science fiction novel from Edgar Award–winning author Matthew J. Kirby that spans both space and time.","forthcoming":false,"isbn13":"9780735231351","publication_date":"20240423","publisher":"Penguin Young Readers Group","slug":"star-splitter","subtitle":"","title":"Star Splitter"},"discovery":{"categories":{"all":[{"bisac_code":"YAF056020","confidence_band":"medium","label":"Space Opera for Teens","score":0.8429,"source":"bisac_hint_model"},{"bisac_code":"YAF056010","confidence_band":"medium","label":"Alien Contact for Teens","score":0.8359,"source":"bisac_hint_model"},{"bisac_code":"YAF001020","confidence_band":"medium","label":"YA Survival Stories","score":0.8269,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"YAF056020","confidence_band":"medium","label":"Space Opera for Teens","score":0.8429,"source":"bisac_hint_model"},{"bisac_code":"YAF056010","confidence_band":"medium","label":"Alien Contact for Teens","score":0.8359,"source":"bisac_hint_model"},{"bisac_code":"YAF001020","confidence_band":"medium","label":"YA Survival Stories","score":0.8269,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"YAF001020","confidence_band":"high","label":"YA Survival Stories","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF056000","confidence_band":"high","label":"YA Science Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF058220","confidence_band":"high","label":"Finding Your Footing","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Space Opera for Teens","score":0.8429,"slug":"space-opera-for-teens"},{"label":"Alien Contact for Teens","score":0.8359,"slug":"alien-contact-for-teens"},{"label":"YA Survival Stories","score":0.8269,"slug":"ya-survival-stories"}],"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"},{"intro":"","slug":"shelf-yaf001020-survival-stories","title":"Survival Stories Books","url":"https://bookfrontier.com/lists/shelf-yaf001020-survival-stories"}],"series":null,"similar_books":[{"authors":["Riley Redgate","Disney Hyperion"],"book_id":"9781368065337","cover_image_url":"https://img.bookfrontier.com/9781368065337.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":19.4845,"title":"Alone Out Here","url":"https://bookfrontier.com/books/9781368065337"},{"authors":["Marc J Gregson"],"book_id":"9781682635766","cover_image_url":"https://img.bookfrontier.com/9781682635766.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":17.0568,"title":"Sky's End","url":"https://bookfrontier.com/books/9781682635766"},{"authors":["E.K.
