What am I reading?

And how is it? Fabulous. This is one I've had on my shelf for ages and ages but for some reason, haven't read it before now. Thoroughly enjoying the humour, the magic, the plot twists and turns, the hopeless/hapless (but determined) hero and his lovely djinni, the inimitable Bartimaeus. Jonathan Stroud is moving up my list of favourite authors of quality fantasy for young readers (along with Garth Nix and Philip Pullman).
