Eh, let's go with 5 stars :) 
 This book was pretty awesome. 
 -> An awesome plot? Check. 
 -> An awesome romance? Check. (It wasn't an instant love, it was one of those slowly progressing ones that didn't dominate the story which only made it that much better!!) 
 -> Awesome characters? Check. 
 Loved it! Awesome job Synder :)
