As promised, here's the summary of Chapter One from Finding Jenna:
Jenna Matthews is home doing homework when her father, Michael Matthews comes home during his shift as a sheriff’s deputy for the Vanderburgh Police Department. It’s very unusual for her father to come home during his shift, and even more unusual for him to come home in his truck. Curiosity drove Jenna to the garage after her father left and she finds the dead body of a young woman in a body bag in her father’s freezer. Jenna realizes she cannot call the local authorities so she called the FBI. Before they could get a team to the house, Jenna’s father returned and took the book away in her mother’s car.
