Echo

Ancient threats don't scare Kaiden Jericho. His partner does.Kaiden Jericho never called himself a hero. Street kids from nowhere survive, scrape, find people worth protecting-and do anything to keep them alive.The job had red flags from the start. A Mirai executive with a grudge. Payment too generous. A Helion facility gone dark for reasons nobody believed. What Jericho Solutions found inside wasn't corporate data-it was a name. The Harvester. Ancient. Patient.Bearing down on a humanity that has 180 years to prepare for something that ended civilizations far older than theirs.Chief has been changing since Echo-7. Kaiden feels it through their bond: his partner's consciousness reaching into systems it shouldn't touch, processing things he won't share. Mirai, Helion, and a government agency called Trinity are hunting them now. Whatever Chief is becoming, everyone wants to control it.Jericho Solutions isn't hiding anymore.Can they build something capable of surviving what's coming-or will the enemies behind them destroy humanity's only advantage before the real war begins?
