The shield is breaking. The world is unravelling.Eighteen months after the fall of the UK, Aegis stands at the centre of a fragile coalition. Nations rise and fracture, armies gather, and across the globe Kronos' cult moves to ignite a war that will burn through every border.From the ruins of Athens to the storm-lashed docks of Norfolk, Aegis fights alongside allies old and new; SAS veterans, US Marines, Nordic commandos, Celtic brigades. But every battle bleeds them dry. Friends are lost, families broken, and time itself bends beneath the hand of the Titan of Ages.For Lily Brooks, command is no longer enough. Forged on Olympus as heir to storm and eclipse, she must lead her team into a final reckoning at Mount Othrys, where the fate of gods and mortals alike will be decided.One by one, Aegis is tested. One by one, the cost is paid. Until only a handful remain to stand against the Father of Time himself.This is their last war.This is their last oath.This is the Unravelling of Time.
