I never expected to inherit a single thing from my cold, elegant mother-in-law, Gloria. But when she passed, the lawyer dropped a bomb: she left everything to me — the house, the savings, even the lake house.

There was just one catch: I had to stay married to my failing husband, Caleb, and live under one roof with his spiteful sister, Tessa, for 90 days. Gloria’s final gift felt more like a setup than a blessing. Caleb was distant and bitter. Tessa, vengeful. And soon, I discovered they were plotting to take it all away. Anonymous complaints, manipulation — even using my kids as pawns.
