Apex (Three Red Women Book 1)

Jane Fairweather has experienced the worst of humanity in her foster homes; whatever potential for normalcy she possessed was shredded after her first assault.
Facundo has been waiting years to find the man responsible for his mother's brutal murder. As a marine veteran, all he wanted was to escape the violence that caused his accident, but he might not be able to resist one last battle.
From the outside, Facundo looks like the monster that Jane is on the inside; she appears to be doll-like, delicate, and immune to the climate of her West Texas hometown. Unfortunately, for the notoriously crime-ridden county, Jane wears two faces.
The Janus-like enigma spends her nights tracking and terminating monsters that prey on the vulnerable. From sexual predators to violent gang members, Jane seeks a hunt. They may be predators, but she is the predator of predators; she is the ultimate, she is the Apex.
