About This Book
The thumping music makes the walls of Happies shake, the smell of popcorn and soda fills the air, and laughter echoes through the night. Vic Navarro’s last big party is buzzing with friends, secrets, and the excitement of summer just around the corner. But when unexpected guests flood the scene, the night turns into something no one could have imagined.
