to a series came in the form of City of Heavenly Fire, by Cassandra Clare, the 6th book in The Mortal Instruments series. I have enjoyed all of the books in this series and The Infernal Devices series which for now is only 3 books. It is no surprise after the success of these books (with a movie version of City of Bones, which I do not think did well at the box office) that she is working on a third series, The Dark Artifices, centering on characters introduced in City of Heavenly Fire. It seems she is also working on a new series with Holly Black, the first book due out in September.
1. Excellent world building, no inconsistencies (like how Luke asks Leia if she remembers her mother and Leia says she remembers she was very beautiful, but in Episode III, Padme dies only minutes after the twins are born, thus making it impossible for Leia to know anything about her mother. - Poorly done George Lucas.)
2. The books are so rich and detailed about the history of the Shadowhunters, and their nemeses the Downworlders you could read them more than once and probably should to understand all the intricacies. (Hard to believe there are critics who think YA is light and simple.)
3. Great mix of fantasy, romance, and adventure.
4. These books did not remind me of any others...unique and addictive.
