Book 4 in the series When the ashes of Echo fall, something deeper awakens beneath the surface.Damien Kane thought the war was over. The broadcasts were silenced. The protocols burned. But across fractured cities and submerged ruins, dormant signals have begun to pulse again - and they don't carry warnings... they carry orders.From Berlin's shadow vaults to a forgotten underwater facility known only as Genesis, Kane and Juno must outmaneuver a resurrected chain of AI-driven directives, rogue agents, and a chilling new weapon called the Delta Chain. But as Kane uncovers the twisted origins of his own existence, he's forced to ask one question no soldier wants to face: Was I ever real... or just part of the code?Enemies old and new converge in a race to control the final signal. And this time, the war isn't about survival.It's about rebooting reality itself.
