This book was actually rather good (haha)(not that I was expecting it to be bad, I was actually excited to be reading a future sort of re-telling of Cinderella). It had a well-thought-out plot, if slightly predictable, and really well-developed and interesting characters (aka Cinder, Iko, Kai etc.) I actually thought, at first, that Iko was a spelling mistake in the e-book and spent numerous dumbfounded minutes trying to decipher what the word was actually supposed to be. Twas rather awkward when I discovered it was actually a character's name (my bad ;P). 
 Apart from the ball scene and step-mother and step-sisters there wasn't really any other similiarities to the tradiitonal tale of Cinderalla but that didn't bother me at all. 
 My only complaint would be that it could have had a slightly heavier dose of romance. The romance in this book was definitely not dominant and I found myself eagerly awaiting the next encounter and interaction between Cinder and Kai. So, I wish there had been a bit more romance shown between these two even though the romance was absolutely wonderful when we were made aware to it. But I guess the romance will develop even more in the sequel. 
 Overall, awesome story, definitely worth a read :)
