At 2 a.m., my sister banged on my door—terrified, with a broken rib—begging for help before collapsing in my arms.

I switched off the living room lamp and crouched beside the couch, peering through a narrow gap in the curtains. His truck was angled across my driveway, headlights still blazing, rain streaming over the hood. Mark stood on my porch in jeans and a dark sweatshirt, shoulders tight, one hand pressed against the door as if he owned everything behind it.
