Sunshine Alvarez-known to everyone as Sun-is the bright light in her group of friends. Always smiling, always listening, always wiping away tears when someone's heart gets broken. As the only girl in an overprotective family of brothers, she's been sheltered, guarded, and raised to be strong. Over time, she developed a rule of her own: never trust guys. She's seen it all-her friends crying over boys who made promises they couldn't keep, who left without warning, who turned love into pain. Sun vowed she'd never let herself fall for someone like that. Never let a guy break her like they did to her girls. Until he came.
