Athena is a group of highly trained vigilante female operatives who tour the world and enact justice on those who prey on and engage in trafficking women. Their one rule is to protect, and not to kill, but Jessie Archer could not restrain herself for a particularly vile target. Now, kicked out of Athena, Jessie starts her own investigation into the target in Belgrade, the mission she was supposed to go on before being kicked off the team. A hunch leads to some serious evidence, but now that she is alone there is no one to watch her back--and worse, her old teammates have orders to bring her down.
