Erin thought she reached a hard-won happy ending. She has a sexy, successful husband, two beautiful daughters, and a life of ease and luxury.
She adores her husband, but she never sees him anymore, and he seems to drift farther away every day. She loves being a mother, but she wants to be Erin too--and she doesn't think she is anymore.
She and Seth have never stopped loving each other. It's just that love can be harder than she thought.
