"I have been stalking my husband's lover." So begins the irrepressible and edgy Terry Spera in this unsettling tour de force about the nature of obsession.

About Yvonne propels us into a startling and erotic journey. We watch as Terry begins to follow Yvonne through the streets of Manhattan, to her apartment on the Upper West Side, and as she begins to make even more alarming inroads into Yvonne's life. As she tries to maintain a semblance of normal life with her husband, Mark, a Soho art dealer, we, like Terry, veer from certainty to uncertainty. Is Mark having an affair?

With a breathless energy and a deeply engaging voice, Donna Masini illuminates the dim and fragmented terrain of an inner life, the vagaries of sexual lives, the difficulty of cultivating a spiritual balance in a city of distractions.
