So far my ranking is (read so far…) goes like this:
Book Eight, Book Two, Book Five, Book Seven, Book Ten Book Six, Book Nine, Book Four, Book One, Book Three.

A slightly different feel, now the lack of solved mysteries is getting a little frustrating. But it is good to see the kids growing up in this series unlike some series in which the children are forever 10 years old.
A few great surprises and a hoo-hum surprise as well.
