2006’s Engaging the Enemy is the third (and middle) volume in Elizabeth Moon’s Vatta’s War quintology.
The book begins where the previous one left off. Ky Vatta is rebuilding her family business, which was laid waste in the previous book. She has managed to acquire her father’s implant, which gives her intimate knowledge of the company (as well as of her father’s final moments before his death). She has defeated her evil relative Osman and has seized his heavily armed ship as spoils of war.
Her troubles are not over, not least because many governments do not accept as legitimate the murder hobo creed “I killed him and then took his stuff.”
