Continuation of Mind Storm (2011) as "psions," mutants with psychic powers, battle it out over the fate of humanity.
Two hundred fifty years ago, nuclear war destroyed Earth and via mutation created the psions, whose weakness is that the more powerful they are and the more they use their powers, the sooner they die. Much of the time it's far from clear what's going on if you haven't read the previous book, or perhaps even if you have, but the planet's two most powerful psions are on opposite sides. Nathan Serca represents the powerful and privileged elite, whose ambition is to escape to Mars. His renegade eldest son, Lucas, intends to stop Nathan and instead reclaim the Earth. Lucas is following the instructions of a four-year-old precognitive relative, Aisling, who died during the war after leaving her plans in encrypted computer files. Lucas' team consists of liberated Strykers, psions enslaved by the government by means of kill switches implanted in their brains. That's really all you need to know. The action is nonstop, insanely violent and mostly lethal, like X-Men on steroids. The biggest problem with all this is that the two Sercas are both homicidal psychopaths, with one slightly less homicidally psychopathic than the other; compassion's in very short supply and mercy isn't even in the dictionary: If somebody gets in your way you kill them, agonizingly and brutally or not so agonizingly and brutally. It's a tribute to Ruiz's skill that, somehow, when a winner finally emerges, it's the one you've been rooting for.
If this book sounds appealing, then read Mind Storm first to avoid at least some of the confusion.
