Archive of the Vanished: Not all who are lost are gone.

She vanished without a trace. Eleven years later, her voice returned. Mira Delane has spent her life chasing sound-lost recordings, emotional echoes, broken frequencies. But nothing prepares her for the cassette that arrives on her doorstep. On it: her missing sister's voice, distorted and frightened. As Mira follows the trail of encrypted tapes and haunted frequencies, she uncovers a terrifying truth: her sister wasn't taken.
She was recorded. And now something-someone-is using that voice to reach back. To rescue her, Mira must descend into a forgotten network of signal chambers, memory manipulation, and artificial echoes of the dead. But some voices don't want to be recovered. They want to replace you. The Echo Collector is a mind-bending psychological mystery about grief, identity, and the power of sound to preserve-or erase-what makes us human.
