Prince Lyon has liked Giselle since seventh grade. Everyone knows it. Giselle calls him "family." Cute. Brother. Important. That's what you call someone you don't want to date. On Monday, she starts dating Jordan Ellis - varsity captain, bus-bench smile, the guy everyone wanted for her. Prince should be happy for her. He's not. He is, however, failing Biology. Again. Tutoring him is Cassandra Jacobs - Giselle's best friend, glasses-always-slipping, both-straps-on-her-backpack, blue-chipped-nail-polish Cassandra. She's tutored him since eighth grade. She times how long it takes him to walk home. She replies to his midnight ceiling posts at 12:01 am on the dot. She's always been there. Right next to his locker. Right across the library table. He just never looked. Until their pinkies touch over a messy, hand-drawn heart with a blue dot in the middle where it hurts. And suddenly Prince isn't sure who he's been in love with all this time.
