It was his mother who died, but Price feels like it was him.
Everything he used to enjoy - baseball, comics, even girls - seems petty and pointless now. He wants nothing more than to forget his old life and start over somewhere new, where no one knows him and no one expects anything from him.
So when his dad decides to move them to the country, he welcomes the change, even if it means cows and dirt roads and crazy neighbors. He doesn't expect to become so wrapped up in the mystery behind their daughter's disappearance that finding out what happened to her consumes his life.
The girl next door is definitely not what he thought she'd be.

Ancient artificial intelligences called Angels are the shadowy guardians of civilization. Over the long ages, humanity has become extinct and reseeded many times. This is the sixth epoch. Little is known about the history of the first five. Responding to a 20,000-year-old radio beacon, an expedition is sent an impossible distance across the galaxy in the hope of recovering knowledge of the origins of the human race. An artifact is discovered in orbit around a dying star. What the crew of the Erebus discovers could mean the end of everything.
