[Quantum Gate 05] • Causality (Quantum Gate Book 5)

It has all come down to this.

Stuck in an alternate universe while Charlie wreaks havoc in their own, Arista and Frees are desperate to return home to stop him. Their only problem: they don’t have a Quantum Gate.

But their new allies are clever, and if they play their cards just right, they might find a way back after all. What they find after being away for months is anyone’s guess.

It turns out things are worse than they ever could have imagined. Charlie has begun an all-out war against the remaining humans and the Peacekeepers, determined to wipe them from the face of the Earth.

And the only ones left to stop him are Arista and her friends. In order to do so they’ll have to seek out the last original Artificial Intelligence, and there’s no telling if he’s even still alive or if he’s willing to help.

CAUSALITY is the final chapter in the pulse-pounding QUANTUM GATE saga. Filled with unforgettable characters and a world in peril, this last installment will leave you guessing until the very end!
