The November/December 2010 issue of The Horn Book carried a starred review of The Ring of Solomon: A Bartimaeus Novel by Jonathan Stroud. I was both delighted and surprised.
I was delighted because I am a fan of the Bartimaeus Trilogy, particularly the third book, Ptolemy's Gate. I'm surprised because Ptolemy's Gate was a very popular book, and I would have thought a new Bartimaeus book (The Ring of Solomon is a prequel.) would have received some pre-publication buzz. I didn't hear any.
However, the book was just published in November, and a quick check of blogs suggests it's being talked about now.
Good luck, Bart.
Oh, and here is a neat little Bartimaeus adventure to hold you over while you're waiting to get hold of his new book. It certainly made me happy.
