Set out for the stars in this warmhearted picture book ode to the transportive power of imagination. Fern and Rosie are astronaut sisters, ready to sail miles above the clouds. They slip on their boots (space boots). They strap on their helmets (space helmets). They pretend the swingset can launch them into the stars, and they lie on the grass gazing up at the real ones. A big space station isn’t the only thing up there—while Fern and Rosie sleep in their rocket ship sleeping bags, their astronaut mom soars through the skies on her way back to earth. They’re more than astronaut sisters. They’re a whole astronaut family! Julie Fortenberry’s Astronaut Sisters is both a heartfelt family tale and tender celebration of just how far our imaginations can take us, pairing warm and whimsical artwork with a sweet sibling relationship. The sisters’ touching reunion with their mother is sure to leave children and parents alike starry-eyed.","forthcoming":false,"isbn13":"9780823458127","publication_date":"20250114","publisher":"Candlewick Press","slug":"astronaut-sisters","subtitle":"Hardcover – Picture Book, January 14, 2025","title":"Astronaut Sisters"},"discovery":{"categories":{"all":[{"bisac_code":"JUV036010","confidence_band":"high","label":"Space & Astronauts","score":0.8588,"source":"bisac_hint_model"},{"bisac_code":"JUV053020","confidence_band":"high","label":"Space Exploration Fiction","score":0.8214,"source":"bisac_hint_model"},{"bisac_code":"JNF051040","confidence_band":"medium","label":"Astronomy","score":0.7903,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JUV036010","confidence_band":"high","label":"Space & Astronauts","score":0.8588,"source":"bisac_hint_model"},{"bisac_code":"JUV053020","confidence_band":"high","label":"Space Exploration Fiction","score":0.8214,"source":"bisac_hint_model"},{"bisac_code":"JNF051040","confidence_band":"medium","label":"Astronomy","score":0.7903,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JUV036010","confidence_band":"high","label":"Space & Astronauts","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV051000","confidence_band":"high","label":"Imagination & Play","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV053020","confidence_band":"high","label":"Space Exploration Fiction","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Space & Astronauts","score":0.8588,"slug":"space-astronauts"},{"label":"Space Exploration Fiction","score":0.8214,"slug":"space-exploration-fiction"},{"label":"Astronomy","score":0.7903,"slug":"astronomy"}],"reader_fit":["For children and parents who enjoy imaginative family stories"],"related_lists":[],"series":null,"similar_books":[{"authors":["Ashlee Hashman"],"book_id":"9780063247840","cover_image_url":"https://img.bookfrontier.com/9780063247840.jpg?v=190d2bf8175bf37c","score":0.8232,"title":"Girls Belong in Space","url":"https://bookfrontier.com/books/9780063247840"},{"authors":["Cathy Hapka","Ellen Vandenberg"],"book_id":"9780593095713","cover_image_url":"https://img.bookfrontier.com/9780593095713.jpg?v=23dcc0e20a31a069","score":0.7836,"title":"Journey to the Moon #1","url":"https://bookfrontier.com/books/9780593095713"},{"authors":["Rie Neal"],"book_id":"9781534481473","cover_image_url":"https://img.bookfrontier.com/9781534481473.jpg?v=e2f0648c1ed8d69b","score":0.7436,"title":"The Astronomically Grand Plan","url":"https://bookfrontier.com/books/9781534481473"},{"authors":["Roda Ahmed"],"book_id":"9780062651730","cover_image_url":"https://img.bookfrontier.com/9780062651730.jpg?v=e17a8d075ae4672b","score":0.7361,"title":"Mae Among the Stars","url":"https://bookfrontier.com/books/9780062651730"},{"authors":["Rob Lloyd Jones"],"book_id":"9781805317470","cover_image_url":"https://img.bookfrontier.com/9781805317470.jpg?v=5add796c33a9bb84","score":0.7351,"title":"Look Inside Space","url":"https://bookfrontier.com/books/9781805317470"},{"authors":["Jaye Garnett"],"book_id":"9781646387755","cover_image_url":"https://img.bookfrontier.com/9781646387755.jpg?v=7f17af26a47f7e30","score":0.7309,"title":"Space","url":"https://bookfrontier.com/books/9781646387755"},{"authors":["Leland Melvin","Joe Caramagna"],"book_id":"9781250782793","cover_image_url":"https://img.bookfrontier.com/9781250782793.jpg?v=f282c15cd32d043e","score":0.7299,"title":"Space Chasers: to the Moon","url":"https://bookfrontier.com/books/9781250782793"},{"authors":["Leland Melvin","Joe Caramagna"],"book_id":"9781250782762","cover_image_url":"https://img.bookfrontier.com/9781250782762.jpg?v=6bc163478a07395c","score":0.7268,"title":"Space Chasers by Leland Melvin","url":"https://bookfrontier.com/books/9781250782762"}],"topics":[{"evidence_refs":["keyword:science fiction for kids"],"label":"Kids","score":1,"slug":"kids"},{"evidence_refs":["keyword:childrens books by age 3 5"],"label":"Childrens","score":0.1936,"slug":"childrens"},{"evidence_refs":["keyword:science fiction for kids"],"label":"Science","score":0.1776,"slug":"science"}],"what_you_get":["Themes: Imagination, Sibling bond, Family reunion.","Themes: Kids, Childrens, Science.","Reading lane: Space & Astronauts and Space Exploration Fiction."]},"llm_signals":{"confidence":0.91,"pacing":"unknown","reader_fit":["For children and parents who enjoy imaginative family stories"],"themes":["Imagination","Sibling bond","Family reunion"],"tropes":[]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":4,"goodreads_ratings_count":87,"goodreads_reviews_count":15,"quality_score":0.8709}}
