My Secret Weapon? A Little Girl!

Clara Clark lives in the Clark house and neither her father nor her mother wants her there. She is their real daughter. She was switched as a small child and grew up in an orphanage, and the Clarks only found her and brought her home years later. The family had also been raising a five-year-old girl called Megan Porter and had turned her out, and Clara takes her in. Megan is a child who carries luck with her. Clara had never had any luck of her own. Once Megan is with her she wins a lottery jackpot, sells the copyright to one of her designs for an enormous fee, and meets a man by chance who turns out to be the one for her. At the Clark house nothing has gone right since the day Megan was put out. The family company's money runs dry and one piece of bad luck follows another.
