Continuity
Michael Kogge's Battle to the End comprises elements of the Star Wars Rebels season-one finale episodes "Call to Action," "Rebel Resolve," and "Fire Across the Galaxy." While the action largely follows material presented on screen, the title occasionally provides insights into the minds of the characters, such as Agent Kallus imagining himself in the place of either the executed Cumberlayne Aresko or Myles Grint, and JJR-579 questioning the loyalty of his fellow stormtrooper JTN-303.
