The Golden Cage by Camilla Lackberg

Revenge is sweet but even better when the person dishing it out is the one person you don't think has it in them. Faye thought being married to Jack was going to be a fairy tale life and set about helping him start his company, raise their daughter and take care of every little one of Jack's needs. That dream turned into a nightmare as soon as Jack wanted out. At first glance, Faye seems ill prepared to handle this turn of events but don't let her "nice person" facade fool you. Lackberg proves once again that tough smart women, egotistical men and revenge is understood in any language.
