Darren Shan: Ocean of Blood (The Saga of Larten Crepsley 2.)

Larten and Wester have cut themselves off from their master, Seba Nile, to run with the Cubs, young vampires who have not yet fully committed to the demands of the clan. They drink and womanise their way across the world, and revel in warfare. Following the death of a friend, Larten and his blood-brother link up with Seba to resume their studies. After they meet with Evanna (and a familiar assistant!) for the first time, Seba takes the pair to Vampire Mountain to train. Larten makes swift progress, but he is unhappy in himself, and feels like he has abandoned the human world too soon. To Wester's dismay, Larten cuts short his studies and sets off by himself. Feeling lonely and purposeless, he is „adopted” by a young woman who has big plans for him. As they cross the world together, Larten has no idea of the dire dangers they will face when they board a ship bound for lands far away, across an ocean that will soon run red with human blood...
