Vampire Princesses and Princes and Vampire Dynasty

Vampire Princesses and princes"My new university is a renovated medieval monastery in Slovakia called 'Dux Ducis' (leader of leaders in Latin). The university is run by professors from all over the world. Monks abandoned it many years ago, not exactly the place an eighteen-year-old girl wants to be, except I don't have a choice. I am Sweden's Crown Princess Paola Katarina. My best friends are Crown Princess Sofia Eleonora from Finland and Crown Prince Oskar Niklas from Norway. The sixth day in the monastery, a soft knock on the door woke me up. I glanced at the clock, and it was 1 a.m. No one was there, but I saw a boy wearing pajamas walking across the garden barefooted. The rigid, slow way he was walking made me think he was sleepwalking. I followed him and a few minutes later he initiated a chilling conversation."Vampire Dynasty"A group of vampire scientists implanted specially designed molecules in all humans' brains to separate healthy blood from the ones who have a sickness, like cancer, AIDS, diabetes, etc. The ones with healthy blood have red nails. The ones with sick blood have brown nails. Many healthy humans have tried to change their red color to brown using polish and other chemicals, and failed. The color disappears within seconds of applying it.
