I Was Only Dreaming

Jessie was 17. She lived in a broken home, listened to rock music, had a tattoo of her astrological sign on her foot, and was a B average in school.
Billie was 17. He lived with his mom and best friend, skipped school, played his music loud, smoked pot, and had a secret he kept from the world.
Mike was 17. He's also Billie's best friend, and Jessie's best friend.
What happens when Billie meets Jessie?
