I often hate sequels, but I just finished the third Olivia Kidney book, and I gotta say-- that Ellen Potter is smart!
I too have longed to write about the old pneumatic train tunnel beneath New York, full of chandeliers and mosaics... about the mole people and the spooks. Damn you, Ellen Potter, for beating me to it!
I loved the William James references! I loved that Olivia was allowed to grow older, but just a little bit.
I did NOT love the lack of illustrations. What's UP WITH THAT? And WHY did they switch cover artists, and WHY did they go back and retitle the second book?
I will never ever understand publishing.
