The Nephew Mastermind

Simon is the uncle nobody in the family consults. His sisters and their husbands go off on holiday and leave seven children with him, which everyone treats as the obvious use for him. Then something switches on in his head, a system that tells him how to bring each child's talent out. Sawyer starts reading the stock market and does not stop being right. Mason learns to treat people with silver needles. Joy enters a draw and wins a mansion. Skylar says things and they turn out to be true afterward. With the seven of them working, Simon stops being the man in the corner of the room. He gets far enough inside a company to find what its executives were hiding and puts the paperwork somewhere it cannot be buried. The Smith heiress, who first met him when he was still a joke, starts seeking him out. He ends up the youngest large shareholder in the family business empire. The holiday ends and the relatives come home to a house none of them recognises.
