Luke is having a rough year. When his parents split up, his mum drags him to Phoenix, a brand-new town in the middle of nowhere. But Phoenix is no ordinary town. There are no cars, no phones and no internet. Luke thinks this is as weird as it gets. Then he discovers that someone is plotting to wipe out the human race. Phoenix is suddenly the safest and most dangerous place on earth. And the clock is already ticking. There are 100 days until the end of the world.

For the first six months, Peter's life in Phoenix was pretty normal. Hanging out with his friends, frustrating his parents, sleeping through school. Then he found out the world was ending. The Shackleton Co-operative is planning to exterminate the rest of humanity - and they're going to use "Tabitha" to do it. But who is Tabitha? What's really going on inside the Shackleton Building? And why does Peter's dad's name keep turning up in the search for answers? As Peter and his friends struggle to contact the outside world, they're going to find out just how far Shackleton is willing to go to make sure the secrets of Phoenix stay hidden. And the clock is still ticking. There are 88 days until the end of the world.

Jordan’s world is falling apart. She’s a prisoner in her own skin, trapped by an enemy who can paralyse her at the touch of a button. And the questions in Phoenix keep piling higher. Why is Jordan starting to see things before they happen? What’s wrong with her mother’s pregnancy? And why do Peter’s old friends suddenly want to talk to him again? The clock is still ticking. There are 70 days until the end of the world.

Luke thought he knew who is enemies were. The Shackleton Co-operative. Calvin, the head of security. The whole town of Phoenix. But then Luke wakes up strapped to a metal chair in an underground lab. There are more enemies - and they've been waiting his whole life to track him down. Meanwhile, up on the surface, the people of Phoenix are beginning to disappear. Are residents finally allowed to leave the desert town, or is the Co-operative taking extreme measures to maintain it's control? But the worst is still to come. Deep under Phoenix, Luke will uncover a secret that changes everything. The clock is still ticking. There are 49 days until the end of the world.

The time for pretending is over. The Shackleton Building has been turned into a concentration camp, and the last free people in Phoenix are forced into hiding. The fight is over unless Jordan and Luke can figure out where the Co-operative is hiding Tobias. And Jordan has to find a way to protect Luke before Peter rages out of control … or else history is doomed to repeat itself. With only weeks left until Tabitha is released, Phoenix’s biggest secrets are still yet to be revealed. And the clock is still ticking. There are 35 days until the end of the world.

There are no more days left. After 99 days of lockdown, annihilation of the human race is right on schedule Luke and Jordan are fighting a losing Battle. Peter has escaped and Bill has disappeared. The Co-operative security are moments away from storming the Vattel Complex. As the battle rages on in town, an offer of help arrives from the last place anyone would have expected. But can it really be trusted or is this one of Shackleton's deceptions? And with murder, still looming over Luke will he even live long enough to find out? One way or another, it's all coming to an end. The clock is still ticking. There are seventeen hours until the end of the world.
