Amy and Dan are shocked to learn that Outcast, a violent renegade who is threatening the lives of innocent people, may be a Cahill family member who is determined to exact revenge.
Probably the worst book yet in the series, the characters feel insanely foreign to me, for some reason kids who spent YEARS escaping from danger by a hair stand still in front of their enemies and the disaster they're supposed to stop wasn't a thing like the name implied. Calling the book "Mission Gateway" would've probably been more accurate, staying on board out of a complitionist's angle since after this luckluster one I only have 2 left.
