It's 2070 and our post-apocalyptic world is different. Aliens secretly invaded with a lethal biological weapon: a terrifying virus that annihilated almost every living creature in its path. People still believe it was a natural virus, oblivious to aliens and the truth. Humanity's survival is in the hands of the alliance, a team of humans and aliens who stand against the evil arch-enemy alien leader. Orphaned children are raised in army-style schools. But from this barren wasteland, a few shall rise...

Tammy and Mikie are half-human and half-alien siblings, with immense metaphysical powers and a crystal weapon. Their powers are extraordinary alone, but together they are unstoppable. Their father promises to return for them when they reach thirteen - combat age. But at twelve, these two are already too powerful to ignore.

Tammy has been raised in an orphan camp, under the thumb of a bitter woman who rules with an iron fist. Now she has been adopted and taken to a new kind of safari park. Here, the scales shift and the animals help her to unlock her gifts with animals and nature. Can Tammy rise above her animal instincts and maintain her humanity?

Mikie, a strong telepath, can control people's minds and is a martial arts expert like his uncle. Forced to live a lonely, home-schooled life to avoid detection, he often gets into trouble and battles with the responsibility of his powers. Can Mikie overcome his inner conflict? Will his compulsion to protect put those closest to him in even more danger?

This adventure will take them across the world and maybe into the stars beyond. They must reunite their family and decide where their loyalties lie. The seekers are coming...
