The Protocol War Books in Order

Kieran wakes without memories and learns that a secret program gives him one year to recover his identity or face execution. A scientist tasked with manipulating him develops feelings that complicate a mission tied to Earth’s survival.

Training as a combat pilot on Mars, Kieran nears a vital breakthrough while hostility toward his program grows. Back on Earth, an artificial intelligence takes human form and seeks revenge, just as authorities condemn him to death.

Kieran joins the defense of an alien ally, but a crisis on Earth abruptly calls him home. A dead enemy’s surviving protocol threatens everyone tied to his program, while his comrades face the approaching battle without him.
