Book Synopsis Finalist for the Arlene Barlin Award for Science Fiction and Fantasy, 2023 CCBC Book Awards Rook and Gage live worlds apart -- but somehow they must find a way to help one another survive. Trapped in a life she didnt choose, Rook struggles to find meaning in her appointed role as an apprentice Keeper of ArHK. Even though her mam soothes her with legends of the Outside and her da assures her there are many interesting facts to discover in the Archives, Rook sees only endless years of tracking useless information. Then one day Rook discovers historic footage of the Chosen Ones arriving in ArHK, and she begins to realize her mams legends are more than bedtime stories. Thats when Rook begins her perilous and heartbreaking search for the limitless sky. Gage is also trapped. Living on the frontier line with his family, his is a life of endless moving and constant danger. As he works with the other scouts, Gage searches for the Ship of Knowledge to help his society regain the wonders of the long distant past, when machines transported people across the land, illnesses could be cured, and human structures rose high into the sky. Will Rook and Gage escape the traps and perils that await them in order to save each others worlds? If they dont, it could very well mean the end of humanity.

The Limitless Sky is an addictive read with an intriguing plot that draws you in from the get-go.-- Candie Tanaka, author and artist The Limitless Sky is a well-balanced cli-fi adventure with a satisfying mystery. Taking a classic science fiction trope -- an isolated population learning they are, after all, not alone in the world -- and unraveling it through the eyes of the young heroes, Gage and Rook, Christina Kilbourne keeps the intrigue high. The likeable protagonists walk through very different worlds, facing very different dangers, but both are equally engaging. The threats never let up as the story unfolds in a wholly satisfying way.

And its only the beginning.-- Helen Kubiw, CanLit for Little Canadians In the futuristic isolated society known as ArHK, where the Outside is a terrifying notion and conspiracy theories abound, Christina Kilbourne captures the existential angst of the blowback from a climate change disaster to perfection. A riveting page turner, poignant and deftly conceived, and quite possibly prescient -- what our planet could potentially look like in a few centuries from now if we dont wake up and smell the smoke. The Limitless Sky is a cautionary tale for the twenty-first century that should be recommended reading at this crucial and pivotal moment in the climactic history of planet earth. Climate change could actually look like this eerie dystopian world sooner than we could ever imagine.-- Deb Loughead, author of The Secrets We Keep Like The Giver and City of Ember , The Limitless Sky opens our eyes to a new take on a dystopian future, and the power young people have to change it.-- Colleen Nelson, Governor Generals Literary Award Finalist for Harvey Holds His Own Rook and Gage are smart and curious teenagers who live far away in a dystopic future that has everything to do with us, here, today. The emotional connection to them is immediate, and the fast-paced narrative makes it impossible to put the book down. As Rook and Gage find answers to their questions, we as readers cannot help but question our own answers to the most pressing issues in our world. The plot is so cleverly woven that it is never predictable and, because this story is as visual and gripping as the most enthralling and successful novels in this genre, The Limitless Sky should make its way to the hands to every reader who enjoys dystopian novels and is up for a great adventure.-- Martha Btiz, author of No Stars in the Sky About the Author Christina Kilbourne is an award-winning author of young adult fiction, most recently Safe Harbour .
