Brimstone, Texas, had gotten very, very hot to live in for Le McCarthy and Marcos Costa. They live together, sharing the secret that they are teenagers who are the sole caretakers of their shared little sister. They need to outwit and outrun the bullies who are trying to make their lives hell because all they need is for Marcos to turn eighteen, graduate, and get to college on his scholarship. Then they can get out of town and never come back.
Meanwhile Daniel Harris has just returned to the small Texas town where he spent time with his grandfather years ago. He had plenty of secrets of his own but he soon realizes that he's not too old to fall for two desperate, frighteningly sexy teens even when that's the absolutely wrong thing to do.
When things get to the breaking point, Harris steps in and all three make a deal to help save the little girl they all want to protect. What none of them want to admit is that they all want something more--something they're sure neither of the other two can handle.
