Two worlds. One artifact. Infinite consequences.

In the neon-drenched sprawl of Neo-Kyoto, tech-savvy thief Kai discovers an ancient artifact—the Echo Key—that doesn't belong in her digital world. When it pulls her across dimensions into the crumbling magical realm of Eldoria, she meets Elara, a spirit-whisperer who claims the Key has awakened a growing fracture between their worlds.

As reality distorts and shadows merge machine with magic, Kai and Elara must form an uneasy alliance. Together, they hold the fate of two realms in their hands. But with time running out, power surging, and a monstrous Tech-Demon emerging from the rift, only one thing is certain:

If the Veil fails, both worlds will fall.

Perfect for fans of Shadow and Bone, Tron: Legacy, and Blade Runner, Echo Key is a pulse-pounding sci-fi fantasy filled with immersive worldbuilding, fierce heroines, and the collision of technology and ancient power.
