They came for Zibba. They stayed for Mara. And now, Jason's caught in the middle of a war he never knew existed.

When Zibba, a quiet alien student hiding on Earth, is tracked by the Syndicate—a relentless interstellar fleet; his human classmate Jason gets pulled into the chase. But the Syndicate's real target isn't just Zibba. It's Mara, a girl who's lived her whole life believing she was human... until her alien heritage awakens and the Syndicate calls her by the title she was never meant to know: Alpha Host.

Hunted across forests, tunnels, and skies filled with glowing carriers, the three unlikely allies discover an ancient relay chamber beneath the earth; a place built for Mara long before she was left on Earth. To survive, they'll have to use her strange resonance power, Jason's unexpected link to it, and Zibba's knowledge of the fleet to unleash a surge strong enough to shut down the Syndicate's network forever.

But ending the threat may cost them everything, and even victory won't silence the hum that now binds them together.
