The key felt heavy in Sarah’s hand, a leaden weight against her palm. She’d been ready to leave for work, finally, but then she saw it. Gone. Her little blue Corolla, missing from its spot in front of her house. A knot tightened in her stomach.

“Well, this is just great,” she muttered to herself, her voice flat and empty. Everything felt like a chore, a burden, a thing to be endured. She was exhausted.
