Castles may conjure up a romantic fairy tale world; however, in real life, during the Middle Ages, castles were fortresses, providing shelter and protection for the lord as well as for the peasants who lived on his land. For an army, a lord depended on young soldiers in armor called knights who spent years at the castle learning the skills of warfare. Author Sarah Fabiny dives into the history of castles and how they grew from simple wood structures to mighty fortresses in stone. She also explains who could become a knight and what their lives were like off of the battlefield, enjoying feasts, courting their lady loves, and showing off in tournaments. With 80 fun black-and-white illustrations and an engaging 16-page photo insert, readers will be excited to read this latest addition to Who HQ!","forthcoming":false,"isbn13":"9780593226865","publication_date":"20220208","publisher":"Penguin Young Readers Group","slug":"what-are-castles-and-knights","subtitle":"","title":"What Are Castles and Knights?"},"discovery":{"categories":{"all":[{"bisac_code":"JNF025100","confidence_band":"high","label":"Medieval History for Kids","score":0.8325,"source":"bisac_hint_model"},{"bisac_code":"JUV016070","confidence_band":"medium","label":"Medieval Tales","score":0.7853,"source":"bisac_hint_model"},{"bisac_code":"JNF025070","confidence_band":"high","label":"European History for Kids","score":0.7827,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JNF025100","confidence_band":"high","label":"Medieval History for Kids","score":0.8325,"source":"bisac_hint_model"},{"bisac_code":"JUV016070","confidence_band":"medium","label":"Medieval Tales","score":0.7853,"source":"bisac_hint_model"},{"bisac_code":"JNF025070","confidence_band":"high","label":"European History for Kids","score":0.7827,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JNF025070","confidence_band":"high","label":"European History for Kids","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF025100","confidence_band":"high","label":"Medieval History for Kids","score":1,"source":"onix_publisher_code"},{"bisac_code":"JNF038060","confidence_band":"high","label":"Europe for Young Readers","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Medieval History for Kids","score":0.8325,"slug":"medieval-history-for-kids"},{"label":"Medieval Tales","score":0.7853,"slug":"medieval-tales"},{"label":"European History for Kids","score":0.7827,"slug":"european-history-for-kids"}],"reader_fit":["Good for readers interested in medieval castles and knightly life"],"related_lists":[],"series":null,"similar_books":[{"authors":["Christopher Gravett"],"book_id":"9780756637699","cover_image_url":"https://img.bookfrontier.com/9780756637699.jpg?v=f37bf9ad7712fa5b","score":0.7819,"title":"DK Eyewitness Books: Castle","url":"https://bookfrontier.com/books/9780756637699"},{"authors":["Richard Platt"],"book_id":"9780763621643","cover_image_url":"https://img.bookfrontier.com/9780763621643.jpg?v=ca47426eb2db57ba","score":0.7765,"title":"Castle Diary","url":"https://bookfrontier.com/books/9780763621643"},{"authors":["Nikola Kucharska"],"book_id":"9783791375656","cover_image_url":"https://img.bookfrontier.com/9783791375656.jpg?v=b8250d18604c8da9","score":0.7695,"title":"A Year in the Castle","url":"https://bookfrontier.com/books/9783791375656"},{"authors":["Katie Daynes"],"book_id":"9781836051398","cover_image_url":"https://img.bookfrontier.com/9781836051398.jpg?v=b1e34d2aad42078f","score":0.7661,"title":"See Inside Castles","url":"https://bookfrontier.com/books/9781836051398"},{"authors":["Richard Platt"],"book_id":"9781465484703","cover_image_url":"https://img.bookfrontier.com/9781465484703.jpg?v=73120a00f108f9a9","score":0.7652,"title":"Stephen Biesty's Cross-sections Castle","url":"https://bookfrontier.com/books/9781465484703"},{"authors":["Joseph Gies","Frances Gies"],"book_id":"9780062016508","cover_image_url":"https://img.bookfrontier.com/9780062016508.jpg?v=d7e4ca0176f32bbf","score":0.7442,"title":"Life in a Medieval Castle","url":"https://bookfrontier.com/books/9780062016508"},{"authors":["Edward Eager"],"book_id":"9780544671713","cover_image_url":"https://img.bookfrontier.com/9780544671713.jpg?v=48108ad873d5eb15","score":0.7441,"title":"Knight's Castle","url":"https://bookfrontier.com/books/9780544671713"}],"topics":[{"evidence_refs":["keyword:nonfiction books for kids"],"label":"Kids","score":1,"slug":"kids"},{"evidence_refs":["keyword:books for 10 year old boys"],"label":"Year","score":0.8411,"slug":"year"},{"evidence_refs":["keyword:4th grade books"],"label":"Grade","score":0.1531,"slug":"grade"},{"evidence_refs":["keyword:5th grade reading books"],"label":"Reading","score":0.0768,"slug":"reading"}],"what_you_get":["Themes: Medieval castles, Knighthood and warfare, Life in the Middle Ages.","Themes: Kids, Year, Grade.","Reading lane: Medieval History for Kids and Medieval Tales."]},"llm_signals":{"confidence":0.91,"pacing":"unknown","reader_fit":["Readers interested in medieval castles and knightly life"],"themes":["Medieval castles","Knighthood and warfare","Life in the Middle Ages"],"tropes":[]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":82,"goodreads_ratings_count":129,"goodreads_reviews_count":14,"quality_score":0.8823}}
