Straight from the Hip: Lone Star Sisters, Book 3 (Unabridged‪)‬

Izzy has always been the fearless Titan sister. But when an oil rig blows up, leaving her barely able to see, her sisters find themselves as concerned by her emotional withdrawal as by the possibility that the explosion was no accident. Are the mind games their long-lost brother Garth has been playing turning physical? Or is someone else out to get them?

When her sisters enroll her in a survivor training camp, Izzy is not happy. Nick, her instructor, is determined that she won't be left in the dark - in more ways than one. But if he tells her the terrible truth behind why he's helping her, he'll never see her again. Unless they're both willing to take the biggest risk of all.
