A satisfying conclusion to a really fun series.
Light years better than the ultra-popular 'Twilight' series, although it seems to draw quite a few comparisons. This is also an Urban fantasy, a sub-genre that's gotten very popular in teen fiction, because it is usually about a very relateable main character that discovers a secret world hidden from normal humans.
If you haven't read the first two books, you shouldn't even bother attempting to read this one, since there's so much going on. I've heard some complaints about how the story is rather predictable, and it is, but it's written in such a way that although you know something will happen before the characters do, it's still fun to stay along for the ride.
My favorite part of this series far and away is the characters. They are three dimensional and are constantly struggling and changing, and emotionally they resonate and seem completely real. Clare really made me care for them, and whenever someone was hurt or struggling with something, I felt it along with them.
I was sad to see the series come to a close, and wished I could spend more time with the characters I had grown to love. I don't re-read books very often at all, but this is definitely a series that I will read again.
