Last book of supernatural soap saga is slightly more mature.
Parents need to know that this series is enormously popular with teen and older tween girls. The main characters -- Bella, 18, mortal, and Edward, vampire -- have sex after they're married. Little is described in detail except that broken furniture and bruises are found on the next day (thanks to vampire super-strength). The goriest part of the book is a supernatural birth scene with lots and lots of blood, cracking bones, and near death. Vampires spend half the book fearing for their lives and the lives of family and friends.
