Ottanger is a rebel and mutant on an Earth governed by a ruthless Committee. But, after the Inspectorate experiments on him, Ottanger realizes his mutation allows him to reach alternate worlds. The multiverse is revealed in all its glory and terror – and he understands that he can finally flee his timeline.
Then Ottanger meets the Fenris, an evolved human visiting his Earth from the far future. He engineered the original world-walking mutation so that those altered could escape the Committee's nightmarish regime. Yet this only worked for a few, while millions continued to suffer. And Ottanger sees that the Committee will become unstoppable if not destroyed.
However, the Fenris has drawn yet another threat to Ottanger's Earth. With the power of its trillion linked minds, the Hive craves world-walking biotech and will do anything to get it. As conflict looms at home and war threatens the multiverse, the Fenris, Ottanger and his companions must prepare for a galaxy-altering battle . . .
