"A Visionary book for 2026" - Space.com
A coming-of-age sci-fi novel about the generation that will decide humanity's future among the stars. On a futuristic Earth transformed by advanced culture, android companions, and interstellar travel, the stars are no longer a dream -- they're a destination. But reaching them demands a price that no algorithm can calculate and no android can pay. Existence Equation follows a group of young people standing at the threshold of an impossible choice. In a world where technology has answered every question, they face the one it can't: what are you willing to sacrifice for something bigger than yourself? As the first generation born into an era of limitless possibility, they must confront the raw, human cost of progress -- and decide whether the stars are worth what they'll lose to reach them. Fusing the emotional intensity of Super 8 with the cosmic scope of Interstellar, Existence Equation is a high-octane journey through a future that feels just close enough to touch. It's a story about ambition, sacrifice, identity, and the question that echoes across every generation: what is the price of the stars? "The Existence Equation is fast-paced, adventurous fun that powers along the cosmic highway."-- Paul Cornell, Hugo Award Nominated, NYT Bestselling Author Perfect for fans of: Super 8, Interstellar, Saga, Paper Girls, and The Hunger Games.
