Query: GREAT BOOK

Of course my favorite parts in the book were Bartimaeus's parts,I love the footnotes also the little snipets about Bartimaeus's past, i hope they play a part in the other books (like who is the boy Bartimaeus liked to turn into?) The Magic is different than in Harry Potter. But this is still a really good book. I am kinda wondering if the next book is going to stay with Nathaniel or if somebody else is going to call Bartimaeus.
