I hope you get this message.
Even though you've posted this message in the NL forum, I'll reply in English for your benefit.
Your blurb; "Duncan's hope" doesn't mean anything to anyone, and doesn't tell us anything of what your story is about.
It doesn't intrigue, and it doesn't tell part of the story.
You would benefit 100% on expanding on that.
Tell us a little more about Duncan, or maybe what his hopes are, or maybe what the 'White Island' is.
I do like the Biohazard sublimely portraid within the cover!
Also, your name doesn't sound English, but you muster the language well!!
I had a quick read of the Look Inside (Not a thorough one, just a quick one) and didn't see any errors.
