Avenger

Mars has been colonized and is a world where children have been replaced by robot servants known as "dolls". The majority of the human population is divided up into a number of small domed city-states. Those who live outside the domes in the harsh wildernesses of the planet are known as Barbaroi. Resources are scarce and supplies are divided between cities based on the outcome of gladiatorial battles between representative fighters from each state. Adding to the problems of the colonists, no children have been born on Mars for a decade. The cause of the infertility is unknown, but people have turned to the dolls as a substitute for the presence of children in their lives. Layla is a skilled Barbaroi fighter with a tragic past. Her companions are Nei, a strange and unique doll with some unknown ties to Layla, and Speedy, a doll breeder or repairman. Volk, the founder of Mars, sees the trio as a threat to the world, and each time they attack Layla and Nei, a bit more of their mysterious past and future is revealed.
