Mystery - Heirs of Aragon, #1

Every twenty-five years, the Aragon Tournament is held among the families of Artilla, Infantra and Caballero. The winner of the tournament will determine which family will rule the Aragon Province for the next twenty-five years. This year, twenty-three-year-old Mystery was chosen to become the champion of the Artilla Family.  She had impressed the elders with her achievements as a fearless professional race car driver and an engineer. One of the strict rules of the tournament was that each of the champions must remain a virgin all throughout the competition.
Because of this, Mystery had never had any boyfriend. But her heart already belonged to Sigfried Torrez who remains unaware of her feelings. Mystery plans to make Sigfried her husband after the tournament whether she wins or loses.
