Wonderland: Virtual Adultery and Cyberspace Love (2007)

"Carolyn is a 37 year-old mother of four in the midst of a passionate affair that is tearing her family apart. She's spending up to 18 hours a day with her lover, and her husband is in despair. But the extraordinary thing about this affair is that Carolyn's lover is man she has never met. Because he's not a human being. He's an avatar (or computer generated figure), who exists only in the virtual world of Second Life. And their relationship exists only in cyberspace."
