Description, from Sam Tomaino (SFRevu): "Myr is one of the soldiers for Crete, fighting Minoa in an endless war. She is locked inside a ship called a mobcom and fights mobcoms from the other side. She has only had to kill twice. Mostly, she just wounds. She even has conversations with her opponents and has some nice talks with Gar, a Minoan. She hears that there is some new weapon that will end the war. She and another Cretan, Gemma, head out on an important mission."
