It’s good to be meta-human, a superhuman hero in a world of normals. Use your superpowers, fight crime, stave off the occasional rogue mutant—then get some rest and have a nice day. But when swastika-laden robotic warriors from an alternate and incredibly advanced Third Reich discover a way to breach the barrier between worlds, the metas face an opponent that will push them to the edge of extinction.And if they can survive the transdimensional menace, the titanic effort will finally push the metas onward to find their true place in society and force them to forge a new, heroic destiny for their kind!

From New York Times best-seller and science fiction and fantasy mistress of adventure Mercedes Lackey, together with a team of topnotch collaborators, the start of a new saga of superpowers—and the very human men and women who must learn to wield them without losing themselves in the process!
The world had become used to the metahumans - people sometimes perfectly ordinary, but sometimes quite extraordinary in appearance - who mostly worked with their governments as high-powered peace officers, fighting crime, and sometimes fighting rogue metahumans who had become super-criminals. Then that comfortable world ended in just one terrifying day.

Suddenly, all world governments were simultaneously attacked by soldiers in giant mecha robotic suits with the swastika symbol of the Third Reich on their metal arms. If these were Nazis, where had they been hiding since the end of World War II? And where had they gotten armor and weapons far in advance of anything on the planet? Weapons against which even the metahuman heroes seemed to be helpless . . .
