Mein Ex ist Geschichte. Ich heiratete seinen stummen Onkel

Beth Carter agrees to a contract marriage with heir Hugh Maxwell to unlock his family trust, only to catch him cheating with her stepsister on their wedding day. She marries Hugh's vegetative uncle Grant instead. Underestimated as a greedy country girl, Beth is actually a math prodigy. She outwits the family, exposes conspiracies, seizes control, and bonds with the mentally awake Grant.
