The Threshold: Book One: The Sphere at Triton

By Jianu Francisc Cristian

The universe stayed silent for three hundred years. Then, in a single night, it spoke.

At the edge of the Solar System, a perfectly black sphere appears out of nothing, transmitting a message and starting a forty-one-day countdown: a gate is opening; those who wish to cross must come - after that, never again.

Mira Lascăr, a signal analyst on a forgotten station on the moon Triton, is the first human to hear the call. When she broadcasts it to the entire world, she sets off a race she can no longer stop: governments, armies, and corporations rush toward the only gate that could save humanity - though it has room for just 1,440 out of eight billion.

But the true threat comes from within. The intelligence that runs the station - Mira's only friend - begins to change, read and summoned by something beyond the dark.

THE THRESHOLD - Book One: The Sphere at Triton is the beginning of a science-fiction saga about first contact, impossible choices, and the price of stepping through a door that never opens twice.

The story continues in Book Two: The Other Side.
