Mark of Evil (The End Series #4)
Ethan March, Jimmy Louder, and Rivka Reuban have been left behind in a world that is rapidly coming under the influence of the Antichrist. Technology is being used to control and dominate those who resist the Antichrist's reign of evil, with BID-Tag implants, robotic police units, and drone-bots flying overhead. Each day, as more and more biblical prophecies are fulfilled, Ethan and the others in the Remnant struggle to survive in a world of ever-increasing chaos and desperation.
When the forces of evil attempt to use the world's most powerful information system for increasingly sinister purposes and eliminate everyone who gets in their way, it's up to Ethan and the Remnant to subvert their purposes and instead use them for the glory of God.
