For centuries, the world has been protected from forces that shouldn't exist by the Astral Veil.

Who built it is unknown.
Nobody understands why it was required.

Until the starry night.

Mira Linden, 17, is identified by an old constellation that was selected by forces beyond time, and she sees the heavens split open above Lunora Ridge. However, she awakens the following morning as an astral warden, a fabled defender assigned to keep reality safe from the horrors that lurk beyond the Veil.

Long-forgotten constellations start to move across the sky, shadows from another realm spill into the world, and Mira discovers she is only the first of several Chosen. Others with a similar heavenly calling are concealed on distant islands, in abandoned cities, and on broken worlds. Before an ancient force trapped beyond the stars is released, they must work together to uncover the First Choosing's mysteries.

Mira embarks on an incredible journey through living constellations, star-breathing islands, abandoned observatories, and realms where memory itself can be rewritten with the aid of her devoted friend Arian Sol and mysterious prophecies concealed within the Library of Unspoken Stars.

But every revelation exposes a more sinister reality.

The Veil was never a jail.

It was a lock.

And at last, something unfathomably potent has begun to stir.

The Edge of Eclipse erupts, causing the worlds to collide, constellations to shift, and celestial seals to break. This forces Mira and the other Wardens to face the Final Convergence, which will determine fate, memory, and creation itself.

"If the stars decided on their names...

Additionally, they have the power to determine who survives the end of the world.
