Death Trials by Darren Shan Synopsis 3

Darren is only half vampire (which means he just drinks human blood), he lives with the vampire clan. He must face five trials to prove he is a worthy vampire, but if he fails he will die. He doesn't know what they are until he is told about it. The normal vampires have to go to the task straight away, but there was an exception made for Darren seeing as he is a half vampire. His trials were interrupted by the vampaneze (who killed their humans) declaring war on them. They murdered everyone, only Darren was left. They hunted him down, and found him in a strong current of freezing water. They wanted him because he was young and had bright ideas, Darren refused and said "I'd rather die!", and with that he was taken away by the current.
