Bound As the World Burns A Post Apocalyptic BDSM Romance

At the end of the world, Cassidy found something she never expected: Love. She was just about to start college classes. She had never been far from home. She was innocent and sweet, and she never dreamed she'd be trapped in a bunker during the apocalypse, with a delicious hunk... Leon. As the outside terrors howl, he teaches her how to please him. They were complete opposites, but soon she realizes just how much she needed a dominant man to take care of her. Is it just a fling as everything collapses around them? Or can something more blossom? Any hope of love will have to contend with the terrors of the ending of the world.
