Contract Wife: Stepmom Rules the Billionaire Empire

Teresa Meireles, an MIT genius and technology executive, accepts a contract marriage worth US$ 10 million a year with Guilherme Cavalcanti, leader of a hundred-billion-dollar empire. Her only mission is to take total control of his three rebellious, spoiled children. Instead of trying to win them over with gentle affection, Teresa launches a fierce, intelligent takeover. She disciplines the chaotic youngest child, drives parasites away from the teenage daughter, and intellectually crushes the arrogant eldest son with advanced options-hedging formulas scribbled on scrap paper. When the glamorous ex-wife tries to reclaim her place, she discovers that the children now loyally support their new, ruthless stepmother.
