From Library Thing:
In her page-turning fiction debut, neuropsychologist Kylie Ladd delivers a searing portrait of two marriages united and betrayed by friendship.
“I had been married three years when I fell in love,” begins Kate, a firecracker of a woman who thought she’d found the yin to her yang in Cary, her sensible and adoring husband. For their friend Luke—a charismatic copywriter who loves women and attention in equal measure, and preferably together—life has been more than sweet beside Cressida, the dutiful pediatric oncologist who stole his heart. But when a whimsical flirtation between Kate and Luke turns into something far more dangerous, the foursome will be irrevocably intertwined by more than just their shared history.
