I Slept With My Best Friend's Boyfriend

I kissed my best friend's boyfriend... because he thought I was her. One mistake should've ended there—until I caught my "perfect" best friend cheating behind his back. Then I heard the truth. "She's boring. Easy to fool." Every kind word, every smile, every year of friendship had been a lie. Now the man I swore to avoid is the only one who knows who she really is. But when he corners me in the dark and asks, "What do you think?"... am I about to betray my best friend—or save us both?
