One forgotten astronomy textbook. A decades-old secret. A fascinating, highly illustrated, epistolary novel perfect for fans of Rainbow Rowell and Alice Oseman, featuring designed doodled edges! When a recent transfer student starts keeping her diary in the oldest textbook at the Green Bank High School library, the last thing she expects is to receive a response. Thus begins a sweeping tale of unlikely friendship and long-buried secrets between two secret pen pals at a rural West Virginia high school. Copernicus is adrift and searching for answers after the sudden death of her mother, and leaving her cosmopolitan life in San Francisco behind. Kepler is a small-town girl with straight A's and big plans to be the first person in her family to go to college, despite her family's modest means. The two girls are so different from one another but united in their goal to solve a mystery that has riddled Green Bank for decades. Meticulously hand-drawn by debut author Jessica Walker across the pages of an actual ancient astrophysics textbook, The Secret Astronomers is a story of friendship, family, crop circles, secret crushes, giant telescopes, life in Appalachia, and two girls discovering new ways to connect across any divide that separates them.","forthcoming":false,"isbn13":"9780593692677","publication_date":"20251104","publisher":"Penguin Young Readers Group","slug":"the-secret-astronomers","subtitle":"","title":"The Secret Astronomers"},"discovery":{"categories":{"all":[{"bisac_code":"YAF056020","confidence_band":"medium","label":"Space Opera for Teens","score":0.7857,"source":"bisac_hint_model"},{"bisac_code":"YAF058120","confidence_band":"medium","label":"Friendship for Teens","score":0.7837,"source":"bisac_hint_model"},{"bisac_code":"YAF054010","confidence_band":"medium","label":"Boarding School YA","score":0.7815,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"YAF056020","confidence_band":"medium","label":"Space Opera for Teens","score":0.7857,"source":"bisac_hint_model"},{"bisac_code":"YAF058120","confidence_band":"medium","label":"Friendship for Teens","score":0.7837,"source":"bisac_hint_model"},{"bisac_code":"YAF054010","confidence_band":"medium","label":"Boarding School YA","score":0.7815,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"YAF011000","confidence_band":"high","label":"Coming of Age","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF016000","confidence_band":"high","label":"Letters & Diaries for Teens","score":1,"source":"onix_publisher_code"},{"bisac_code":"YAF058120","confidence_band":"high","label":"Friendship for Teens","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Space Opera for Teens","score":0.7857,"slug":"space-opera-for-teens"},{"label":"Friendship for Teens","score":0.7837,"slug":"friendship-for-teens"},{"label":"Boarding School YA","score":0.7815,"slug":"boarding-school-ya"}],"reader_fit":["Readers who enjoy illustrated, epistolary stories about unlikely friendships","Readers drawn to teen mysteries involving secret pen pals"],"related_lists":[],"series":null,"similar_books":[{"authors":["Alexa Donne"],"book_id":"9780063335585","cover_image_url":"https://img.bookfrontier.com/9780063335585.jpg?v=84d88461184cfaa6","score":0.7382,"title":"The Stars We Steal","url":"https://bookfrontier.com/books/9780063335585"},{"authors":["J.
