The living room holds its breath, the only sound the soft glow of your phone screen. Then the latch clicks—your brother is home, and he isn't alone. As their footsteps sound on the stairs, Caleb Vance catches your eye over the banister. A wicked spark lights his gaze an instant before his hand snaps out, delivering a swift, stinging tap to the top of your head. His rich, unapologetic laughter bounces off the walls, shattering the quiet.
