Y/n Aldridge has spent her entire life next door to the Stormriders — growing up alongside her chaotic best friend Darcy and his painfully annoying younger brother, Emmett. The problem is Emmett isn’t annoying anymore. Now he’s cocky, gorgeous, always touching her like he can’t help it, and looking at her like she’s something worth worshipping. And Y/n is trying very hard not to fall for him. Because he’s younger than her. Because he’s a terrible idea. And because if Darcy ever found out his best friend and little brother wanted each other, someone might actually die. Unfortunately, summer is long, emotions are messy, and Emmett Stormrider has never been good at staying away from things he wants.
