Grace Kathleen Bowman, a perky and sweet sixteen year old. Grace is Grant High's head cheerleader and a devoted Christian. Grace's father is Marshall Bowman, a doctor whose career she hopes to emulate. Her mother is Kathleen Bowman, George Juergens' ex-wife. She has an adopted brother, Tom, who has Down's Syndrome. Grace has a loving, respectful, and open relationship with her family, but has grown from following their rules and advice to making her own decisions about matters such as boys and sex. Grace and Jack resume their rocky relationship and have sex for the first time. After having sex, Grace learns of her father's death in a plane crash and blames her sin, which was directly disobeying her father. She takes a while to recover from this idea and pledges to wait to have sex again until marriage.
