After re-reading this a second time, I'm going to bump it up to 4.5 stars! 
 I realised how amazing this is and noticed all the small things that I didnt catch on the first time reading it. So many hidden clues! Brilliant. 
 _____________________________________________________________ 
 It's pretty awesome. Not as epic as i thought it would be, but it's still good. Plot was good, I LOVED THE CONCEPT OF THE DIFFERENT LONDONS. The characters were amazing, both have totally different personalities and thinking that they complement each other. Absolutely loved their chemistry. 
 I cant choose who I love more, Kell or Lila. I love that Kell was strong and vulnerable at the same time. He is quite by the rules kind of guy while Lila was not. (Thats why they match). 
 Lila is cool too because of her sassy attitude and fearless and wow. I just have a soft spot for strong, independent women. My weakness. 
 Ship her and Kell together, though it wouldve been better if there were more subtle scenes together. Sorry, I just love slow, burn romance and it's the little things that matter a lot. And, I do like her and Rys too. I can see an impending love triangle but I dont dread it, I can tell that it s not gonna be a pain in the tush. 
 Hmm my complaints would be the last fight was not as epic or engrossing as it could have been. I wish there were more characters, like secondary characters. Would definitely be awesome. And before the two characters meet, it was kinda slow. 
 Absolutely love they way they met. Hilarious it was the scenes Lila made a Kell clone. 
 I wished there were more epicness. Buttersweet ending BUT THANK GOD THERES A SEQUEL. WILL DEFINITELY READ IT. YESS. WE LL FIND OUT THEIR BACKGROUNDS. 
 DEFINITELY RECOMMEND, BUT dont have such highhh expectations.
