The Last Champion — Peter Bostrom

Admiral Jack Mattis thinks Spectre, humanity's nemesis, has been defeated. And he sacrificed the USS Midway to do it.

Now a US Navy pilot has gone missing. A terrorist group kidnaps a dozen infants. Admiral Mattis's own infant grandson is suddenly and mysteriously ill with a sickness no doctor can--or will--diagnose. No one can piece the puzzle together, until from a derelict future-human ship Mattis finally recovers an actual mutant human, come from the future to destroy Spectre himself.

Because humanity's greatest nemesis is not dead--he is only now ramping up his plan for galactic domination. And the pieces he sets in motion will force Admiral Mattis to make the unthinkable choice between saving a billion people, or saving his only grandson and a dozen other infants.

Spectre must be stopped.

And only one champion can stop him. Or die trying.
