What happens when we lose everything that makes us human?

===

In the final days of 2025, the world learns its fate: a supermassive black hole, thirty-seven times the mass of Sagittarius A, is barreling toward the Milky Way at a tenth the speed of light. As panic and chaos sweep the globe, scientist Dane Currier and his brilliant team at the University of Washington race against extinction. Their only hope lies in Project Courier—a radical teleportation technology that could offer humanity a second chance on a distant exoplanet.

But the path to salvation is fraught with peril. Each breakthrough brings new dangers, from grotesque teleportation failures to a mysterious cognitive affliction spreading across the planet. As governments seize control and society unravels, Dane and his allies must risk everything to perfect a system that could save a chosen few—or doom them to a fate worse than oblivion.

The Slide by Aaron Ryan is a pulse-pounding blend of hard science, emotional stakes, bittersweet sacrifice, and existential dread. Follow Dane Currier and his team as they race to perfect a radical teleportation technology, risking everything to escape extinction. With grotesque teleportation failures, a mysterious cognitive affliction, and society unraveling, every page is a fight for survival—and for what it means to be human.
