Despite being turned off by books starring teenagers(what can I say, I was suicidal my whole adolescence and I don't like being reminded), I loved this series. The characters, the action, the humour...I only wish Cassandra Clare had written more than three! If you are only going to read one young adult series, I'd still recommend Twilight, but if you are going to read two, this should be the second. It's not as introspective and wordy as Twilight, but the emotional content is there, and the magic is amazing. You'll also meet more creatures than just vampires and werewolves.
My original review of City of Bones from weRead:
Not as good as the Twilight Series, I have to say. The author seems to rush over details to get to the action, which makes it a fast-paced story, which is great, but is not 'fleshed out' in a way that will stick with you. I did love how much lore was woven into this book, and have started the next in the series. It is entertaining once you get used to the lack of writing flourish.
Author's note (March 2013): I'm not sure what I was thinking when I wrote this review. In retrospect, I would probably recommend The Mortal Instruments over Twilight, though I stand by my star ratings for both. I enjoyed them both, despite the horrid Twilight movies.
