Three SCUBA instructors, who happen to be sexual dominants, are about to take the ultimate plunge. If you’re extraordinarily lucky, you’ll be invited to join them on The Divemaster, where work and pleasure go hand in hand. Welcome aboard!

When her mentor is killed in a lab fire, all his notes destroyed with him, marine biologist Sabine Reynolds is determined to finish his work—a cure for an aggressive form of cancer. She needs a specific coral to continue. To find it, she boards The Divemaster to search the waters around Hawaii.

Crewmember Miguel Torres helps facilitate the collection…and brings out a sensual side of Sabine she hadn’t known existed. In the warm tropical waters, she discovers fascinating things about herself and the taboo fantasies she’d never experienced before meeting the sexy guide, who isn’t afraid to take charge during their daytime, and nighttime, adventures.

The Divemaster crew come face-to-face with danger in the form of rival researchers, who’ll stop at nothing to ensure their success at Sabine’s expense. Sabotage, theft, kidnapping, murder, whatever it takes to produce—and profit from—the cure first.

Can Miguel keep Sabine safe and by his side? Or will her enemies put a stop to her research…permanently?
