Rhybor has been liberated ... for now. But the vengeful Kauri will return.

King Helion knows the clock is ticking, and that Rhybor's shapeshifting wehrdragons can't defeat the Kauri cyborgs alone. But the Kauri don't just threaten Rhybor. The aliens' bold plan to 'optimise' the universe makes them a threat to everyone - so a galactic response is paramount.

As the king of Rhybor races to build his Galactic Alliance to counter the impending invasion, the three Earth-born teens who were instrumental in beating the Kauri into retreat now face their greatest challenge. Elvira, Felix, and Liberty endure the brutality of Rhyborian politics as they fight their way to the front line to battle the Kauri, and it will scar each of them physically and emotionally. Friendships and loyalties will fray into tatters.

As battle with the cyborgs looms, will the trio fight alongside each other as friends, or will they simply be united in hatred for a common enemy?
