Married To My Sister's Billionaire Widower

After my sister died, I thought the worst part would be the grief.

I was wrong.

The "will" left me a choice that wasn't a choice at all: walk away and lose everything she died protecting... or marry Noral Vane-her billionaire widower, the cold man who looks more like a weapon than a husband.

One year. No scandals. No questions.

But the moment I step into the Vane empire, the "accident" that killed my sister stops making sense. Missing evidence. Wrong dates. People smile too politely while they warn me to let it go.
