What are the motifs in Angry Housewives Eating Bon Bons by Lorna Landvik?

Secrets are a recurring idea in the book. Everyone has a secret. The women of the angry housewives are no exception. Merit lives for several years the victim of domestic abuse before her friends learn the truth. Audrey hides a sixth sense that enables her to intuit events before they happen, like the fact her husband is cheating on her. Kari keeps secret the true identity of her daughter's birth mother for almost thirty years. Slip hides the fact that her cancer has returned. However, none of these women live with a secret as big as Faith's.
