It's their daughter's graduation and Rachel and Ed Hartley are expecting it to be one of their family's happiest days. But when she stumbles and falls on stage during the ceremony, a beautiful moment turns to chaos: Gemma has been shot, and just like that, she's fighting for her life.

PI Matthew Hill is one of the first on the scene. A cryptic message Gemma received earlier in the day suggests someone close to her was about to be exposed. But who? As Matthew starts to investigate, he finds more and more layers obscuring the truth. He even begins to suspect the Hartleys are hiding something big--from him and from each other.

While Gemma lies in hospital in a coma, her would-be killer is still out there. Can Matthew unravel the family's secrets before the attacker strikes again?
