There's power and passion in three. When Carly Kenan joined the secretive Trinity Masters in college, she knew that one day she'd have to pay the piper. That day has come. Returning to Boston, Carly meets former Marine Lance Glassco, a mathematician for DARPA, and Preston Kim, a celebrated chemist. Though on the surface they have nothing in common, it's clear the Grand Master thinks that together the three of them can do something amazing. And that's why he's declared that Carly, Lance and Preston must unite. In a ménage. Tempers flare as they struggle to understand each other, but their physical attraction is explosive, and the sex leaves all of them begging for more. Pushed beyond her limits, Carly runs from Lance and Preston. What she doesn't understand is that she now belongs to them, body and soul...and they belong to her, too. When Lance uncovers a dangerous crime in Preston's firm, Carly is caught in the crossfire and the struggling lovers are forced to move beyond desire...to trust. The Trinity Masters have the power to make careers and change lives, but there's a price. All members know that the day will come when the Grand Master will select them, and pair them with two others. For the Trinity Masters the strongest bond isn't a pair, but a threesome.
