Chicago cop Nick watches his roommate, best friend and secret crush Riley marry the intriguing Lily. He has no idea of Riley's true feelings for him, or the fact that Lily knows and accepts them.

Dominant Lily wants to give her beloved everything he needs in bed and beyond, even if that means quiet and controlled Nick. Deep down, she suspects the equally dominant Nick is someone she may need as well. Lily pushes a physical encounter and no one is prepared for the intensity of their feelings and desire.

Sex—in every combination possible—is the easy part. The conflict comes when each panics over their increasing emotional connection in their own way. Lily needs control, Nick fears commitment and Riley doesn't feel he deserves two amazing lovers.

And when a stranger threatens their relationship, their careers...and their lives, Riley, Lily and Nick will need to rely on each other like never before.
