Hex on the Beach by Aurora Grey

She’s a witch trying to escape her dark past. A lust demon is the last thing she needs in her life…

Ven fled Raven’s Roost to get away from bad memories—a toxic relationship and a harrowing near-death experience with a demon. The warm breezes of Costa Rica seem the perfect place to forget it all… until her friend Luciana goes missing.
She’ll do anything to find her friend, and that means working with cocky playboy and supernatural tracker Ryder. Who just so happens to be a lust demon. She can’t very well forget the past when she’s got another demon to contend with.
Ryder likes his relationships hot, fast, and temporary, and he’s got a century of one-night stands under his belt. But Ven doesn’t fall for his magic like everyone else. She’s gorgeous and powerful, and risks tearing down the walls he built around his heart long ago.
Which makes it very inconvenient when a spell misfires and they end up trapped in a magical orb that prevents them from moving more than three feet away from each other. Ryder’s always liked a challenge, but this is pushing even his limits…
To make matters worse, what seems to be a simple missing person case is far more sinister. Ven and Ryder find themselves up against one of the most powerful supernatural crime organizations in the world. If they can’t learn to work together fast, it’s more than their hearts on the line.
