The Metashiftors saga continues! Teratron and his band are desperate. Betrayed by their comrades and routed by the return of the legendary Decatron, their escape leads them leads back to the last place they’d hoped for - Earth. Marooned in the galactic equivalent of nowhere, with their own internal tensions threatening to tear them apart, they take a dangerous gamble that puts them in the crosshairs of both the other Illusicons and the Mechabots. And if two factions of Illusicons, a vengeful runaway teenager and Rigel’s undercover operative weren’t enough for the Mechabots to deal with, an even more sinister threat takes root in the very shadows of their home world: the Goryu. Their monstrous armies, now including reanimated Illusicons in their ranks, begin a systematic invasion that heeds no lines of allegiance or decency. Can the Mechabots decipher Tutami’s warnings - and protect her legacy - in time to stop three enemies at once?
