Culpability by Bruce Holsinger

The Cassidy-Shaws are driving to son Charlie's lacrosse match when they are in a car accident that kills both people in the other car involved. Charlie was in the driver's seat of the family's self-driving car and grabbed the wheel right before the collision. The dad, Noah, was in the front passenger seat. Mom Lorelei was in the back of the vehicle, behind the two other kids in the family--teenagers Izzy and Alice. Lorelei, Izzy and Alice are injured and all five family members are traumatized by what happened. They wonder what the police investigation of the accident will bring. They then decide to rent a house for a week to get away, but the home turns out to be near tech billionaire Daniel Monet's compound, and he seems to already know Lorelei. Lorelei, who is a MacArthur fellow, professor at Johns Hopkins and a foremost authority on AI, denies any connection. The relationship between the two families is further complicated by the beginnings of a romance between Charlie and Monet's daughter Eurydice. Over the vacation, lies are exposed and the family's bonds are tested. A read-alike for Elin Hilderbrand, Jodi Picoult, and Hazel Says No.
