Cussing: Yes, frequent throughout.
Alcohol, Drugs, etc: Some drinking, some teen drinking, but not much at all.
Sexual Content: Just your typical discussion/narration/joking teenage stuff. Some euphemisms.
Disturbing Images/Violence: Some plot stuff that regards incest, a scene or two involving a homosexual relationship (which, incidentally, didn't bother me at all, on the contrary in fact, but I know that some people have a problem with it).
Review (or something):
This "review" is different for several reasons. 1) I don't want to give away anything from the last two books to anyone who hasn't yet read them. 2) My ratings from the first book, City of Bones, apply pretty consistently to the rest of the series. 3) I read them back-to-back as if it were all just one book, and it seemed pretty pointless to review them both separately in that case. So, I hope you don't mind. Here you go!
Wow. What a storyline! This series is EPIC. It has all the twists and turns and shocks of a great action movie, while telling a beautiful tale of love and acceptance and conquering evil. Told with natural, easy-to-read writing, The Mortal Instruments was a trilogy to remember. These are the kind of books that get under your skin and invade your dreams.
A lot of people have read them, and for good reason. They appeal to a variety of audiences. Male and female readers alike can relate to the characters, and whether you like dangerous, adventurous, supernatural, modern, old-timey, otherworldly, biblical, unique, or romantic, there's something here for you.
EDIT 10/16:I have received word that there will be a FOURTH BOOK in this series for release in March 2011, titled CITY OF FALLEN ANGELS! Also, a prequel series to Mortal Instruments, called INFERNAL DEVICES trilogy, is also underway. The first book, THE CLOCKWORK ANGEL, will be available September 7, 2010. The following books will be titled The Clockwork Prince and The Clockwork Princess. Oh boy! This means we still have FOUR BOOKS to look forward to from Cassandra Clare!
