Star Wars: Rogue One - Cassian & K2SO Annual (2017)

The Rebel Alliance relies on the sharp instincts of Cassian Andor, one of its most effective field agents. His operations are now supported by the tactical analysis of his partner, K-2SO, a former Imperial security droid. Their current cohesion belies a hostile origin. The details of their initial encounter on a remote Imperial outpost are finally coming to light. The confrontation was defined by mutual distrust and conflicting protocols, a violent first contact between a dedicated spy and a lethal machine built for enforcement. The memory core of the droid still contains the raw data from that day.
