[Siren Menage Everlasting: Erotic Menage a Trois Romance, M/F/M, HEA] Structural engineer Autumn Johnson only has eyes for her career. But destiny throws her a twist that puts Engine Company Lieutenant Zach Torren and lead paramedic Casey Macon in her sights. She's had her fill of obnoxious men in the fire service, but Zach and Casey are determined to show her how hot and enjoyable fate can be. Zach knows how to put out fires. He knows how to keep them burning, too. The spontaneous flames that erupt when he meets Autumn need fuel, not water. But, someone wants her dead and, in the end, he'll need skill more than charm he to keep her alive. It's been years since a woman caught Casey's heart. Autumn does it on sight, but is she everything Zach thinks she is? When her life is threatened, he pushes that question aside and focuses on keeping her safe. But, when he discovers who's behind it all, it might be too late. ** A Siren Erotic Romance
