Assassins. Time-stoppers. Aliens.
One man stands between Earth and total annihilation.

A former assassin with a dark past, Raven now dedicates his life to protecting the innocent. His world turns upside down when Rainey Livingston emerges from a time-displacement portal, wielding the impossible power to freeze time itself. Protected by the genetically enhanced warrior DC, Rainey is being hunted by the Central Technology Agency and its ruthless director.

As an alien invasion looms on the horizon, Raven discovers a horrifying truth—twelve years ago, he had the contract to kill Rainey. Now, they must work together to uncover the truth behind Rainey’s extraordinary abilities and his connection to the alien threat. With the CTA deploying their deadliest weapons and time itself working against them, Raven must now protect the very person he was once paid to eliminate.

Time-Stopper is the fourth pulse-pounding installment to Jeffrey Poston’s acclaimed Call Sign: Raven science fiction thriller series. If you crave adrenaline-fueled action, complex conspiracies, and mind-bending sci-fi, then you’ll love Poston’s explosive new thriller.
