I think there amazing. As soon as I finnished the 1st book they were my new favs. Even though I hadn't read the segundo one, (the 3rd wasnt out yet) best libros eva!!!
the are absoloutly the best and favourite series I've ever read in my whole life. Finished all the 4 books, and Clockwork ángel por Cassie too. Can't wait for the siguiente ones. They're just that much addicting.
