I love reading about vampires, so i was excited for this too. It sounded quite different from others, revolving around vampires who reside on an island, where sun doesn't shine ever. Sofia is kidnapped and taken there, where she meets prince Derek who has just woken from a long sleep, and if she doesnt impress him, she could become his next meal. 
 I found Sofia a cool protagonist; she was brave, confident and courageous but at times i found it a bit unrealistic. I would be quite terrified if i found myself on an island full of vampires where i m to be a "slave" but she never showed much fear. I liked Derek and the romance between him and Sofia, even though it was a bit too quick. I liked how Derek cared about her and listened to her. 
 Ben was a cool character though i didn't really get the point of him in the story. I absolutely detested Lucas and he was a cool villain. There were a lot of other characters that i wanted to read more about but sadly they didnt get much development. 
 Overall, i thought the book was pretty good but could have been a lot better if it was longer. There could have been more development of plot and characters as i thought some things happened quite fast. The cliffhanger was interesting so i m curious to see what happens next.
