The October Daye series is so far my favourite of everything by Seanan McGuire / Mira Grant that I've read. The first books were sort of average-but-enjoyable-enough UF, but the last few that I've read (haven't quite caught up yet) have been great, at least for me.
I started
Lockwood & Co: The Whispering Skull by Jonathan Stroud last night. Didn't get very far yet. After loving Stroud's Bartimaeus series to bits, I really had high hopes for
Lockwood & Co. but the first book, while being okay enough, didn't really grab me (not in a "wow" way in any case) last year and this one seems to be much the same way, although there are now hints at some deeper plot that may, if I'm lucky, turn out to be what I need... Still, I don't think this series will make it to my top ten unless something really remarkable happens either in this book or the next.
