Re: What Fantasy/Sci-Fi book have you just finished? Please rate it...
Just finished Turn Coat (Yay for libraries that ignore street dates).
Spoiler free commentary.
I thought it was one of the best in the series. It did have some obvious transitional stuff, and set up for future bits, but most all the recent Dresden books have had that.
We get some more info on Harry's mom, lots of info on the White Council, and most every secondary character (except the Carpenters) appears in the book somewhere (even if just for a cameo). Harry is actually planning things a little more ahead, and there is serious butt kicking. There are also a number of things that end up sad for Harry... but things are hopeful at the very end, even with the bittersweet moments.
Highly recommended.
