He started it

"Beth, Portia and Eddie are siblings. Like all siblings, sometimes they don't get along. They just have better reasons than most. But when their grandfather dies, he leaves a troublingly specific condition in his will. For them to inherit his wealth, they're required to retake a road trip they took with him when they were children, and scatter his ashes at the end of it. Of course, reuniting after all this time brings back memories of that ill-fated trip. Memories of what went wrong. But that's not all they have to worry about. Someone is following them. Each of them is keeping secrets. And all of them are all too aware of what happened last time. Because you can't inherit the money if someone kills you first."--Provided by publisher.
