 The title of "Change of Command" refers to two events that drive the plot and occur just before the story begins or very early on.The first is the assassination of Bunny, or Lord Thornbuckle.The attack is believed by most to have been engineered by the New Texas Godfearing Militia who had sworn to git revenge on Thornbuckle and the Familias Regnant in general for executing Our Texas's leaders, the Rangers (for what they did to Brun and other women in "Rules of Engagement").
