While picking out a new suit for an upcoming TV appearance to promote her latest novel, celebrated mystery writer Iris MacKenzie has an unfortunate altercation with her ex-husband's very pregnant new wife. When video footage of the incident goes viral, Iris's career comes crashing down around her. Her publisher drops her; her literary agent drops her; and even her lawyer, who happens to be her own son, drops her.

As she is sifting through the ruins of her life, Iris gets a call from a woman working at a local rehabilitation facility, claiming to represent a patient there who would very much like to speak with her. When Iris tries to pump the woman for information on who this mysterious patient could be, all the woman will tell her is that she believes Iris holds the key to the patient's journey toward recovery.

Given Iris's current emotional state of mind after the destruction of her career, she's not inclined to grant this patient's wish, but for reasons even she herself can't explain, Iris agrees to pay this patient a visit. When she shows up at the facility the following day, the patient turns out to be the last person she ever expected to see.

What follows is a beautifully written story about love, loss, hope, redemption, and the indelible and unbreakable bonds that tie us together as we travel through this journey we call life.
