In 23 Years on Fire, Cassandra discovered that the technology that created her has been misused in her former home and now threatens all humanity with catastrophe. Returning home to Callay, she finds that Federation member worlds, exhausted by the previous thirty-year-war against the League, are unwilling to risk the confrontation that a solution may require. Some of these forces will go to any lengths to avoid a new conflict, including taking a sledgehammer to the Federation Constitution and threatening the removal by force of Cassandra's own branch of the Federal Security Agency. More frighteningly for Sandy, she has brought back to Callay three young children, whom she met on the mean streets of Droze, discovering maternal feelings she had not known she possessed. Can she reconcile her duty as a soldier, including what she must do as a tactician, with the dangers that those decisions will place upon her family--the one thing that has come to mean more to her than any cause she now believes in?","forthcoming":false,"isbn13":"9781616148959","publication_date":"20140408","publisher":"Pyr","slug":"operation-shield","subtitle":"A Cassandra Kresnov Novel","title":"Operation Shield"},"discovery":{"categories":{"all":[{"bisac_code":"FIC028050","confidence_band":"medium","label":"Military Sci-Fi","score":0.8007,"source":"bisac_hint_model"},{"bisac_code":"FIC028100","confidence_band":"medium","label":"Cyberpunk","score":0.7727,"source":"bisac_hint_model"},{"bisac_code":"FIC028030","confidence_band":"medium","label":"Space Opera","score":0.7717,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"FIC028050","confidence_band":"medium","label":"Military Sci-Fi","score":0.8007,"source":"bisac_hint_model"},{"bisac_code":"FIC028100","confidence_band":"medium","label":"Cyberpunk","score":0.7727,"source":"bisac_hint_model"},{"bisac_code":"FIC028030","confidence_band":"medium","label":"Space Opera","score":0.7717,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"FIC028050","confidence_band":"high","label":"Military Sci-Fi","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC028100","confidence_band":"high","label":"Cyberpunk","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Military Sci-Fi","score":0.8007,"slug":"military-sci-fi"},{"label":"Cyberpunk","score":0.7727,"slug":"cyberpunk"},{"label":"Space Opera","score":0.7717,"slug":"space-opera"}],"reader_fit":["Good for readers who enjoy Military Sci-Fi","Good for fans of Science Fiction","Good for readers who enjoy Military Sci-Fi and Cyberpunk."],"related_lists":[{"intro":"","slug":"shelf-fic028030-science-fiction-space-opera","title":"Science Fiction Space Opera Books (fiction)","url":"https://bookfrontier.com/lists/shelf-fic028030-science-fiction-space-opera"},{"intro":"","slug":"shelf-fic028050-science-fiction-military","title":"Science Fiction Military Books","url":"https://bookfrontier.com/lists/shelf-fic028050-science-fiction-military"}],"series":null,"similar_books":[{"authors":["Philippa Ballantine","Julienne Irons","Blackstone Publishing","& 0 more"],"book_id":"9781789099942","cover_image_url":"https://img.bookfrontier.com/9781789099942.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":9.1539,"title":"Alien - Inferno's Fall","url":"https://bookfrontier.com/books/9781789099942"},{"authors":["Ian Douglas"],"book_id":"9780061978999","cover_image_url":"https://img.bookfrontier.com/9780061978999.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":8.9826,"title":"Star Marines","url":"https://bookfrontier.com/books/9780061978999"},{"authors":["Mike Resnick"],"book_id":"9781591026952","cover_image_url":"https://img.bookfrontier.com/9781591026952.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":8.923,"title":"Starship: Rebel","url":"https://bookfrontier.com/books/9781591026952"},{"authors":["Jeffery H.
