Code Word Delta: Volume 4 (Paperback) (ISBN-13: 9781646307913)

Two sides of a shattered world. One chance to save it.

Twenty years ago, an EMP blast stopped Apex--a powerful AI bent on human extermination--and split the United States in two.

West of the Rockies, technology is outlawed and society has reverted to 19th-century ways under the strict rule of the Organites. East of the Mississippi, Apex still controls a hyper-modern world hurtling toward technological singularity. Between them lies a war-torn no-man's-land, where both sides fight for dominance.

Adam, the restless son of the legendary rebels who triggered the blast, longs to join the fight but is stuck scavenging the wastelands with his parents' caravan. No one knows he's broken a cardinal rule--using forbidden tech to secretly befriend Joan, a young soldier-in-training from Apex's side.

When Adam uncovers a threat even greater than Apex, he must convince Joan to risk everything to work together and reactivate a forgotten defense system before it's too late.

But neither of them knows the truth about their past--a secret that could destroy their bond . . . and reshape the fate of humanity.
