When every mother's worst nightmare becomes Grace's reality, she must examine her entire life -- from the wrong choices to the right mistakes.

Grace's son Jack is a miracle. At three years old, he's fighting a mysterious, deadly disease that his doctors predicted would kill him as a baby. Even though it was determined to be mitochondrial disease, the little-known illness remains a mystery to medicine. Grace has sat by his bedside every minute he has been in the hospital, questioned every diagnosis, every medicine -- even poring over medical journals and books at home late into the night. To the world, Grace's fierce dedication is the sole reason for her son's survival. But someone suspects that perhaps Jack's disease is not what it seems.

When an allegation of Munchausen Syndrome by Proxy is leveled against Grace, she begins to live in constant suspicion of everyone -- from the doctors and nurses surrounding her son in the hospital to her own husband. Who could possibly think that she has been purposely making her son ill to gain attention for herself?

Although her husband believes their life is exactly as it seems to the outside world, Grace knows differently. She is harboring a secret -- the adulterous affair she's having with her first love. But perhaps her biggest betrayal of all is her shameful uncertainty about whether she's chosen the right path, the right husband, the right life.

In this compelling and heartbreaking novel, critically acclaimed author Maribeth Fischer addresses how the choices we made yesterday can affect everything that lies before us.
