yes, its disturbing that 10 year olds read this..but when you put into account that a lot of them drink, smoke, do drugs, and most already know about sex..its not that big of a deal any more..yeahh, 20 yeards ago..it would be insane..but times have changed..
i'd say teenagers..13 - 17 mostly..because thats a girls "fangirl" stage..and god knows how many of them are crazy over edward..and plus..the more mature readers would get annoyed by the simple writing..
