I know it is a very long shot and i am quite ashamed to ask you this, but i need help remembering a book's name.
Long story short i had this book on electronic format on my old harddrive that blew up and for the love of god i can not remember it's name and it's author, although i enjoyed it very much.
I only read half of it and i would like to finish.

My memories are scarce because it is allmost 1 year since i've read it but as far as i remember the story went something like this : A young singer can command dragons with his songs , although he doesnt know it yet. There are a clan of dragon riders that rule the world , they are villains. One particular scene remains in my mind , when one dragon raider rapes a girl in the stable and she is terrified because the dragon raiders are said to kill every-one they made love with because of their blood.

Damn, now when i read what i wrote above it sounds corny as hell , but it was a good book, serious fantasy writing , and i would really apreciate your help. Thank you.
