I still remember how this book tore me apart. I was thankful I read this book before Heavenly Fire because of SPOILERS. Anyway! I still can't decide which of the trilogy I enjoyed the most but let me tell you that they were spectacular! I consider the Infernal Devices so much better than the Mortal Instruments. Parabatai feels, brotherly feels, ship feels and all of them tore me apart. Can we just talk about the epilogue of this book?! OMG. So great! Highly recomended. 
 (view spoiler)[ what I didn't like about this book is that she practically ended up with both. but yea... (hide spoiler)]
