Time has veered wildly off course, and now the first moves are being made that will lead to a devastating world war and the fall of the British Empire. Caught in a tangled web of cause, effect, and inevitability, little does Burton realize that the stakes are far higher than even he suspects. A final confrontation comes in the mist-shrouded Mountains of the Moon, in war- torn Africa of 1914, and in Green Park, London, where, in the year 1840, Burton must face the man responsible for altering time: Spring Heeled Jack! Burton and Swinburne's third adventure is filled with eccentric steam-driven technology, grotesque characters, and bizarre events, completing the three-volume story arc begun in The Strange Affair of Spring Heeled Jack and The Curious Case of the Clockwork Man.","forthcoming":false,"isbn13":"9781616145354","publication_date":"20120124","publisher":"Pyr","slug":"expedition-to-the-mountains-of-the-moon","subtitle":"","title":"Expedition to the Mountains of the Moon"},"discovery":{"categories":{"all":[{"bisac_code":"FIC027260","confidence_band":"medium","label":"Romance Adventure","score":0.7538,"source":"bisac_hint_model"},{"bisac_code":"FIC028060","confidence_band":"medium","label":"Steampunk","score":0.7536,"source":"bisac_hint_model"},{"bisac_code":"FIC009100","confidence_band":"medium","label":"Fantasy Adventure","score":0.7383,"source":"bisac_hint_model"}],"hint":[{"bisac_code":"FIC027260","confidence_band":"medium","label":"Romance Adventure","score":0.7538,"source":"bisac_hint_model"},{"bisac_code":"FIC028060","confidence_band":"medium","label":"Steampunk","score":0.7536,"source":"bisac_hint_model"},{"bisac_code":"FIC009100","confidence_band":"medium","label":"Fantasy Adventure","score":0.7383,"source":"bisac_hint_model"}],"publisher":[{"bisac_code":"FIC009030","confidence_band":"high","label":"Historical Fantasy","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC014000","confidence_band":"high","label":"Historical Fiction","score":1,"source":"onix_publisher_code"},{"bisac_code":"FIC027070","confidence_band":"high","label":"Regency Romance","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Romance Adventure","score":0.7538,"slug":"romance-adventure"},{"label":"Steampunk","score":0.7536,"slug":"steampunk"},{"label":"Fantasy Adventure","score":0.7383,"slug":"fantasy-adventure"}],"reader_fit":["Good for readers who enjoy Romance Adventure","Good for readers interested in historical","Good for fans of Steampunk"],"related_lists":[],"series":null,"similar_books":[{"authors":["Johnston McCulley"],"book_id":"9781649740151","cover_image_url":"https://img.bookfrontier.com/9781649740151.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":16.6894,"title":"The Mark of Zorro","url":"https://bookfrontier.com/books/9781649740151"},{"authors":["Mark Hodder","Gerard Doyle","Audible Studios","& 0 more"],"book_id":"9781616143596","cover_image_url":"https://img.bookfrontier.com/9781616143596.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T16%3A15%3A58Z","score":15.243,"title":"The Curious Case of the Clockwork Man","url":"https://bookfrontier.com/books/9781616143596"},{"authors":["H.
