A writer and graduate student at the University of Southern California, the bisexual Vanessa lives in a polyamorous triad with married couple Anthony and Vanessa. She's known Anthony since they were both kids, and was the Maid of Honor at Lindsey and Anthony's wedding. After moving in with the couple, she first became lovers with Lindsey, who she'd admired from afar for many years, then with Anthony. While committed to the triad, Vanessa often feels like the third wheel to Lindsey and Anthony's marriage. In a society such as ours, will she ever feel like a legitimate partner to the couple she loves?
