A Royal Love: Royals of Solniana

This is the third book of 'A Royal Love'. The story Follows the first and second book, but it takes place several years later.

My name is Mirella, but my family calls me 'Ella'. I'm twenty and I'm the crown princess. I have one sister, Lucy and two brothers: James and Jason. I'm the youngest of us which is normal because the king and queen don't get more children once they have an heir. Once an heir is born, the queen can't get children anymore. An heir has a golden shine in the eyes, while the others don't have that. Which means that there's only one heir, my brothers and sister haven't got the right to be king or queen. That's why I'm protected by everyone, because when I would die, there's nobody that can become king or queen.
