Every time another book in this series comes out, I completely fail to notice its release until it suddenly appears on the NEW Fiction shelf, at which point I snap it up immediately and wonder why I wasn't paying closer attention.
And then I read the book and remember that, while the two authors should manage to create something incredible, what they usually manage is a fascinating but forgettable puzzle-box. The science-fictional idea that drives the story is still really cool, but the people get less and less interesting as the series goes on. It is, as I've been reminded, very much worth reading, but not worth expending the energy of actively looking forward to it.
Wow, that sounds like I hated it. I didn't; it was perfectly fine and I'm glad I read it. I just want it to be spectacular. Is that so much to ask?
