the Constantine weres and the Renier weres have had centuries of fueding. Jacob Constantine is Texas Ranger, married to gentle Ruth, but he left her too often - and the Renier's killed her. He carries the guilt, left the Rangers, became a bounty hunter, and lived by a Code of justice.
until he is ambushed when taking a murderer in, is tied up, beaten up, no food or water, and Serenity and company rescues him. Serenity has founded Avalon Ranch, where women run everything (there are 8 of them). They reluctantly take wounded Jacob - who quickly recovers (as soon as he has strength to Change, he is fine).
Serenity was raised Quaker, and she survived when her family and fiance were killed for no reason by the Reniers - they then held her captive for a year, raping her at will. She escaped, took a lot of ther money, and bought Avalon Ranch with a few other women - successfully working it for the last 4 years - with more women coming. Zora, half Apache half white and were, is one of the bunch.
And Jacob stays on to help with branding (to pay his debt)... and the gang shows up, and they take the leader alive, losing one of theirs to his gun. He wants to take him in for justice, the women overrule him - but before they can hang him, Jacob shoots him, to save Serenity the eventual guilt she will feel.
And they are warming up to Jacob, especially Serenity - he keeps to himself, he works hard, he supports them... and Serenity hires him to go after the Reniers - he reluctantly agrees, knowing she'll go after them herself if he doesn't... and he tempers the Code with their needs.
And on the way, Serenity finally gives up her need for revenge - after putting 3 friends at risk (another ex ranger bounty hunter tries to take one of the friends for killing her abusive husband before he killed her)... and she goes home, to her ailing aunt.
and on their journey, they get closer. Serenity finds she trusts him, she finds that she is attracted to him... and Jacob restrains his attraction, but starts to hope that she might care.
And in the end, when they find honesty and passion and forgiveness, the Reniers take parts of her Quaker family hostage, and they capture Jacob through trickery, and Serenity and hers once again rescue them. And for those who do not die, Jacob takes to justice, waiting until their trials are complete... and he goes home to Avalon. ahhhhh
and Zora departs when he arrives - to find herself... the next book?
