One hundred and fifty years ago, the first dinosaurs were cloned. Soon after, they replaced humans at the top of the food chain. The only way to survive was to move into underground compounds. . . . Five years ago, Sky Mundy’s father vanished from North Compound without a trace. Now she has just stumbled on a clue that not only suggests his disappearance is just the tip of an even larger mystery, but also points directly to the surface. To find her dad—and possibly even save the world—Sky and her best friend, Shawn, must break out of their underground home and venture topside to a land reclaimed by nature and ruled by dinosaurs. Perfect for fans of Brandon Mull, Lisa McMann, and Rick Riordan, this exhilarating debut novel follows two courageous friends who must survive in a lost world that’s as dangerous as they’ve always feared but also unlike anything they could ever have imagined.","forthcoming":false,"isbn13":"9780062416230","publication_date":"20170502","publisher":"HarperCollins","slug":"edge-of-extinction-1-the-ark-plan","subtitle":"","title":"Edge of Extinction #1: the Ark Plan"},"discovery":{"categories":{"all":[{"bisac_code":"JUV016090","confidence_band":"medium","label":"Prehistoric Stories","score":0.7945,"source":"bisac_hint_model"},{"bisac_code":"JUV002060","confidence_band":"medium","label":"Dinosaurs & Prehistory","score":0.792,"source":"bisac_hint_model"},{"bisac_code":"JNF025150","confidence_band":"medium","label":"Prehistoric Times","score":0.7915,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"JUV016090","confidence_band":"medium","label":"Prehistoric Stories","score":0.7945,"source":"bisac_hint_model"},{"bisac_code":"JUV002060","confidence_band":"medium","label":"Dinosaurs & Prehistory","score":0.792,"source":"bisac_hint_model"},{"bisac_code":"JNF025150","confidence_band":"medium","label":"Prehistoric Times","score":0.7915,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"JUV001010","confidence_band":"high","label":"Survival Stories","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV001020","confidence_band":"high","label":"Pirate Adventures","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV002060","confidence_band":"high","label":"Dinosaurs & Prehistory","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV002070","confidence_band":"high","label":"Dog Stories","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV002190","confidence_band":"high","label":"Pet Stories","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV002340","confidence_band":"high","label":"Jungle Animals","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV002360","confidence_band":"high","label":"Nocturnal Animals","score":1,"source":"onix_publisher_code"},{"bisac_code":"JUV028000","confidence_band":"high","label":"Mysteries & Detective Stories","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Prehistoric Stories","score":0.7945,"slug":"prehistoric-stories"},{"label":"Dinosaurs & Prehistory","score":0.792,"slug":"dinosaurs-prehistory"},{"label":"Prehistoric Times","score":0.7915,"slug":"prehistoric-times"}],"reader_fit":["Middle-grade readers who enjoy action-packed dinosaur adventures","Tween readers drawn to mysteries and dangerous lost worlds"],"related_lists":[],"series":null,"similar_books":[{"authors":["Marc J Gregson"],"book_id":"9781682635766","cover_image_url":"https://img.bookfrontier.com/9781682635766.jpg?v=ebdc92fc4a61b5b4","score":0.7392,"title":"Sky's End","url":"https://bookfrontier.com/books/9781682635766"},{"authors":["Royden Lepp"],"book_id":"9780593565391","cover_image_url":"https://img.bookfrontier.com/9780593565391.jpg?v=d8512698b6665f55","score":0.7317,"title":"Jurassic Jeff: Space Invader","url":"https://bookfrontier.com/books/9780593565391"},{"authors":["Brenda Cooper"],"book_id":"9781633880504","cover_image_url":"https://img.bookfrontier.com/9781633880504.jpg?v=11c6e4e9ed1465bf","score":0.7213,"title":"Edge of Dark","url":"https://bookfrontier.com/books/9781633880504"}],"topics":[{"evidence_refs":["keyword:middle grade"],"label":"Grade","score":0.1531,"slug":"grade"},{"evidence_refs":["keyword:adventure"],"label":"Adventure","score":0.0897,"slug":"adventure"},{"evidence_refs":["keyword:middle grade"],"label":"Middle","score":0.0679,"slug":"middle"},{"evidence_refs":["keyword:friendship"],"label":"Friendship","score":0.0515,"slug":"friendship"},{"evidence_refs":["keyword:survival"],"label":"Survival","score":0.026,"slug":"survival"}],"what_you_get":["Themes: Survival among dinosaurs, Friendship, Finding a missing parent.","Pacing: fast, momentum-driven storytelling.","Story elements: Missing-parent mystery, Underground refuge, Dangerous expedition."]},"llm_signals":{"confidence":0.94,"pacing":"fast","reader_fit":["Middle-grade readers who enjoy action-packed dinosaur adventures","Tween readers drawn to mysteries and dangerous lost worlds"],"themes":["Survival among dinosaurs","Friendship","Finding a missing parent"],"tropes":["Missing-parent mystery","Underground refuge","Dangerous expedition"]},"source_presence":{"amazon":true,"book_detail":true,"goodreads":true,"llm_signals":true,"similarity_seed":true},"stats":{"amazon_ratings_count":602,"goodreads_ratings_count":1949,"goodreads_reviews_count":252,"quality_score":0.9437}}
