<human>: When I was younger, I loved Jenny Nimmo's books in the Children of the Red King series.  I read Midnight for Charlie Bone and the follow up book, Time Twister. I bought both books on the day of release and was an excited 10 year old when I asked a member of Waterstones whether or not there would be any more in the series. To my dismay she told me there would be no more books. I accepted this, and now I'm 21 years old and have discovered there's another 6 books in the series. Is the series worth reading at my age, or is it aimed at an audience much younger than myself?

Can you condense the text into a few key points?
<bot>: Read first 2 books in series, bookstore worker told me there would be no more. I'm now 21 and discovered there's more books. Should I read them at my age
