In a world where every human possesses a spiritual reflection living in a parallel universe, an ancient mystery surfaces: people across the town of Elderglen begin disappearing right after speaking to their reflections in mirrors.

Emily Ashcroft, a quiet orphan who repairs antique mirrors, lives a life of solitude—until the day her reflection whispers her name. When she discovers that the image in the glass not only mimics her but also thinks and plots, she is drawn into a hidden war between worlds.

Soon, Emily is recruited by a secret organization known as the Guardians of Purification, committed to protecting reality from an imminent invasion by beings known as Mirrorborn. These reflections yearn to trade places with their human counterpart, and the portal that allows them through only opens once every hundred years.

But as the line between reality and reflection begins to blur, Emily faces an impossible question: What if she isn't the original... but the reflection that has already crossed over? Torn between two identities and in a race against time, Emily must decide whether to sacrifice everything to close the mirror world or accept the truth that could change both worlds forever.

A captivating and compelling fantasy novel about identity, sacrifice, and the thin veil between light and shadow.
