The Sisterhood: a group of women bound by friendship and a quest for justice. Now their male allies, the Men of the Sisterhood, have formed a top-secret organization of their own, with the same goal of helping the helpless and righting the wrongs of the world....

Loyalty is a way of life for the Sisterhood and their significant others. When lawyer Lizzie Fox's husband, Cosmo Cricket, is left critically injured after being shot by an unknown assailant, the men of BOLO Consultants head straight for Las Vegas to comfort Lizzie - and to uncover a dangerous enemy in the City of Sin.

As head of Nevada's Gaming Commission, Cosmo has powerful enemies. Yet the shooting seems to be related to one of his private projects. Built in the desert outside Las Vegas, Happy Village is a flourishing community for seniors who have lost a spouse. Cosmo's widowed father found new purpose in running the venture. But the neighborhood that's now home to Happy Village was once run by rival gangs, a complicated past that has come to haunt the place. Jack, Harry, and the rest of the crew need to remove the threat, risking everything to take on a vicious and mysterious gang leader known only as Hot Shot. And while the men of the Sisterhood fight for justice for their friend, Cosmo is fighting for his life - and the stakes have never been higher....
