Echoes That Burn

Something is erasing the Unwritten - and it isn't the Archive.
When an Unwritten settlement vanishes with no Archive resonance signature, Dr. Kael Voss and the crew of the Tesseral face a threat no one anticipated: an organization with its own erasure capability, operating entirely outside cosmic law. As navigator Pira Sung's echo sickness escalates from intrusive melody to uncontrollable visions - faces, names, the specific weight of civilizations that no longer exist - she begins to transform into something the mission didn't plan for and cannot afford to lose.
Forty hours of fold-prep. A war fleet parked three hundred kilometers away. A question that has been building across two books that finally gets asked in the quiet hours of a nav bay at 0200. It doesn't end with a kiss. It ends with something harder and more real.
And when the fold completes and ECHO surfaces from its own deep memory, it finally knows what it was before it was ECHO. The answer is twelve thousand years old. And it changes everything.
Echoes That Burn is the third book in the Crystal Archive Chronicles - an epic space opera about memory, erasure, the ethics of a perfect record, and what survives when history gets it wrong.
