This is the continuation of Cave World. Alex and the women escape from their caves and journey to a far continent on their colonial world. In order to establish a safe community, they must defeat three different kinds of aliens who are hostile to their settlement. They must win over organic poisons, sophisticated firearms and telepathic manipulation which compromises some of the women. They must also learn to live with extreme gender imbalance starting with only one male and slowly growing to over 10 and about 120 women.
