I don't know if I am reaching the end of my enthusiasm for YA lit, or just had enough of nephilim hijinx but I didn't particularly love this. Perhaps it has been too long since I read CoFA, I don't know. Clare's writing has never been stellar but I always found her books fun and engaging, exciting and enjoyable. CoLS felt choppy with endless to-ing and fro-ing between scenes/characters. The repetitive phrases I didnt notice in other books were obvious and grating. It felt like a collection of little love stories tacked together - jace&clary, isabelle &simon, jordan &maia, magnus &alec.... 
 I missed the real Jace, I missed the witty sarcastic comments, I found myself not really caring what happened. 
 I will probably read the final instalment in this 2nd trilogy but beginning to think Clare should have left it with 3 books.
