- Description from novelbuddy

Teela married King Heavenly because she loved him, but life in the Heavenly household was anything but euphoric. Lettie, her hard-as-nails mother-in-law, treats her like an unpaid servant. The family treats her like an outsider. King treats her like a shadow, transparent and forgettable.When Lettie presses Teela to prove her value to the family or get out, Teela has a decision to make. But she’s not leaving without a fight.King Heavenly rules Heavenly Industries with an iron fist, but he leaves his home life to his mother to manage, and that includes the management of his boring little wife. Teela has never complained. She’s never done anything interesting, for that matter. She’s just one more responsibility in a long line of responsibilities that King shoulders on a daily basis, and that is exactly how he treats her — as a responsibility that he’s delegated to his mother.Suddenly Teela steps out of the shadows and into a fight with him and his whole family, and King is baffled by the ruthless actions of his now daring wife. He’d always heard that vengeance is a dish best served cold, but Teela is coming in hot!

Yuki, a high school junior, dies heroically saving a stranger and is reincarnated in a fantasy world, where he discovers an extraordinary and unrivaled power.
