Query: Bartimaeus: no age restriction

Like some other series, Bartimaeus is not simply for the younger generation. A wonderful and addictive read, I found many sleep deprived nights to be a symptom. Not of the horror within the book, but because I couldn't put it down! I had to read just one more chapter; and then another, and so on.I'll put it this way: I bought all three books less than a month ago. I'm finishing up the last book, as I write this. As much as I need more sleep than I've been allowing myself, I wish there were more to come!Highly recommend to anyone from 10 years old, to a few decades, too!
