Zeph finally has a potential lead to Amy’s kidnapping: Jemmah—the last person Amy called on homecoming night. Meanwhile, Qiana and Amy venture into the Lords of Lore to find Sophi. When she offers to help them escape the FCP, Amy finds herself torn between seeing her family again and helping Qiana with her quest. A fragment of the ancient Babyloyptian scroll may provide answers, but it may also lead to more questions… Regrets are voiced and deep wounds are healed in this latest volume of Stephen McCranie’s Space Boy .","forthcoming":false,"isbn13":"9781506747149","publication_date":"20250325","publisher":"Dark Horse Comics","slug":"stephen-mccranie-s-space-boy-volume-21","subtitle":"","title":"Stephen Mccranie's Space Boy Volume 21"},"discovery":{"categories":{"all":[{"bisac_code":"JUV008140","confidence_band":"medium","label":"Sci-Fi Comics","score":0.8315,"source":"bisac_hint_model"},{"bisac_code":"JUV053020","confidence_band":"medium","label":"Space Exploration Fiction","score":0.8106,"source":"bisac_hint_model"},{"bisac_code":"YAF010030","confidence_band":"medium","label":"YA Sci-Fi Comics","score":0.8,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JUV008140","confidence_band":"medium","label":"Sci-Fi Comics","score":0.8315,"source":"bisac_hint_model"},{"bisac_code":"JUV053020","confidence_band":"medium","label":"Space Exploration Fiction","score":0.8106,"source":"bisac_hint_model"},{"bisac_code":"YAF010030","confidence_band":"medium","label":"YA Sci-Fi Comics","score":0.8,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JUV008140","confidence_band":"high","label":"Sci-Fi Comics","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV053010","confidence_band":"high","label":"Alien Contact","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV053020","confidence_band":"high","label":"Space Exploration Fiction","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Sci-Fi Comics","score":0.8315,"slug":"sci-fi-comics"},{"label":"Space Exploration Fiction","score":0.8106,"slug":"space-exploration-fiction"},{"label":"YA Sci-Fi Comics","score":0.8,"slug":"ya-sci-fi-comics"}],"reader_fit":["Good for readers who enjoy Sci-Fi Comics","Good for fans of Graphic Novels","Good for readers who enjoy Sci-Fi Comics and Space Exploration Fiction."],"related_lists":[{"intro":"Season 4 introduces Thragg and pushes Invincible into darker moral territory;
