Before I get into it, I must note that the primary thing that deducted from my enjoyment of the book was how long it took me to finish the book (and how many gaps between listening there were due to library loans being automatically returned).
That being said OH MY WORD. I love Will and Jem's bromance; they complements each other so well. I do, however, feel that the romance suggested between the two boys and Tessa was unnecessary (as all the same things still could've happened were they just friends, and Tessa truly had no reason to love either of them, and them, Tessa). Clare did write each character in a beautiful way, though. Often, I felt I could reach out and slap them across the face — both an euphoric and infuriating (in a good way) feeling.
I also feel that Clare wrote the intermingling of the supernatural and the ordinary in such a facinating, believable way.
All in all, I enjoyed this book.
