Cari Mora by Thomas Harris (Silence of the Lambs)
There is a vast amount of gold buried under a former drug lordís Miami beachfront home, and some very bad men want to claim it. They also want to claim the mansionís caretaker, the beautiful and scarred Cari Mora.
But Mora was a child soldier in the Columbia guerrilla wars, and she knows a thing or two. She wonít be easily bested by the villains.
Interesting look at a small part of Miamiís Latino community, including the undocumented, and a great story about a total badass.
If you want a happy ending, that depends, of course, on where you stop your story.
