Tortured by guilt for killing his mother, in post-pandemic Britain, Peter Grant is still haunted by the fiery holocaust that he devised to ensure his victory at Llyn Edno.
He has found a passionate love with Branwen, the feisty warrior and clan leader of the Red Dragons.
But his family brings with it new challenges and responsibilities, and he struggles to make sense of his roles as war leader, father and husband in this fractured, conflicted world.
Spurred on by the deaths of his mentors, Chad and Daniel, Peter seeks to protect his people by forging a path to peace with the adversary he thought he had defeated five years before.
Just when it seems his hopes might be realised he finds himself facing an enemy he did not know existed, an enemy so pitiless, so numerous, that it could lay waste to friend and foe alike, an enemy of such horrendous proportions that for the first time Peter faces utter defeat.
This time he won't be able to kill his way to victory.
As Britain plunges once more into chaos will a young woman with the Sight and her warrior sister be the Saviours, or is there yet another threat looming, just over the horizon?
