Can society survive in a world where humans live for generations? Professor Herbert Blane's Life-Extension Therapy (LET) has changed the world, allowing humans to live for centuries. The first recipients of LET-the so-called early generations-amassed wealth and power with no intention of ever stepping aside. Now, society is fractured. Younger generations find themselves scrambling for resources, forced into cities where skyscrapers stretch a mile into the sky, leaving streets in perpetual twilight. As resentment deepens, the New Generations Initiative (NGI)-a covert network of disenfranchised scientists, engineers, and strategists-rises to challenge the ruling elite. Led by scientist Boris Bagan and joined by Cynthia Wu and Curtis James, two brilliant researchers from Blane's own lab, NGI launches an underground movement that engages in daring acts of sabotage to fight for a future worth living for. But will their revolt be enough to heal a broken society? Will they be remembered as traitors . . . or the only ones brave enough to change the future? Subtraction is a gripping exploration of ambition, rebellion, and the cost of scientific progress.
