On the surface, these seven women are as different as can be - but each has had her share of bad luck, from cheating husbands to sexist colleagues to a legal system that often doesn't do its job. Now, drawn together by tragedy, they're forging a bond that will help them right the wrongs committed against them and discover an inner strength they didn't know they had. The Sisterhood is learning that when bad things happen, you can roll over and play dead...or you can get up fighting...

Through public triumphs and private sorrows, the men in the Sisters' lives - husbands, friends, colleagues, and lovers - have offered invaluable aid and support. In the process, they've become an informal brotherhood of their own, able to relate to the unique challenges and rewards of life among the vigilantes.
