Contract Wife: Savage Stepmom Rules the Billionaire Empire

A brilliant technology strategist signs an eight-figure marital agreement with a mega-billionaire patriarch, tasked with bringing order to his three uncontrollably defiant children. Eschewing passive coddling, she treats the dysfunctional household like an optimization puzzle, using psychological precision and advanced mathematical formulas to disarm each rebellious child.

She disciplines the unruly youngest boy, severs predatory grifters exploiting the teenage daughter, and intellectually humbles the eldest heir over complex financial markets. When the children's manipulative biological mother attempts to reclaim her status, she is stunned to find the heirs fiercely shielding their indomitable new stepmother.
