Bound as the World Burns — Alexis Abbott

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 serve and please him. Between them, something amazing blossoms and 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.
