La Petite Voyageuse du Temps

Mia suffered under her aunt Amelia since childhood. At ten, she saw her mother Olivia die in an asylum and learned Amelia had schemed to marry Logan in Olivia's place. Burned to death, Mia returned ten years earlier. At Amelia and Logan's engagement, she revealed the truth and used prophecies to win Logan's trust. He discovered Amelia had tried to cause Olivia's miscarriage and brought Olivia home. The adopted daughter Aria caused constant trouble, but Mia's prophecies foiled each plot. Aria kidnapped and framed Mia, ending in prison. Mia helped Logan's firm go global, then vanished at Olivia and Logan's wedding.
