The cover is nice. That's the good news. 
 I didn't like the "dying teenager" story in the beginning. 
 The writing style is hideous; way too desperate to please YA/Tumblr users. Stories inspired by old legends are hardly ever adapted into something good, especially not by US American authors. More proof right here.
