Undone is a story about sexual jealousy and obsession told from the perspectives of two women. Nathalie is a journalist in Washington DC who has always relied on her gut instincts, but when she begins to suspect that her husband is cheating on her, she wonders if she is just being paranoid. After all, she is prone to anxiety attacks and still emotionally scarred by her ex-husband’s infidelity. Determined to uncover the truth, her investigation into the woman she believes her husband is sleeping with becomes an obsession that she refuses to let go of, even when it becomes clear that her behaviour is crossing the line. And who is Trudi? A single mother and aspiring writer who wants to leave more of a mark on the world than her work allows. Her comfortable life begins to fall apart, though, when her different worlds collide.
