The end of the world is coming, or so they say, and that puts Bailey Dewitt on a crash course with Armageddon. Orphaned, she and her young brothers find themselves living with their renegade uncle as part of a group of survivalists. She struggles against them, searching for a way to escape, but every discovery only terrifies her more. For Caleb Cross, the Ranch is a way of life. The members of their group are family, and none should come between them. Smitten from the moment he met Bailey, his choices are no longer easy, his path no longer clear. He wants to welcome her and the twins into their fold and hopes his kin will agree. But the elders who lead them aren't interested in the troublesome girl. They are plotting for the time they will be rid of her and expect Caleb to go along with their plans - he is after all one of them. At first, Bailey resists Caleb's charms, but soon must admit that she desperately needs a friend. She has no intention of anything more, but when the elders make their move, she is forced to trust him with her very life. They both have hard lessons to learn. Relationships built on secrets and lies don't come with guarantees. When the world falls apart around them, some things are Irrevocable.
