Wormwood - Susan Wittig Albert Almost every time I go back to a series, I wonder why I dropped it in favour of other books. This was no exception. Definitely worth the time, even if only for the herbal knowledge. I had the whodunit figured out early on, but I was wrong about the hows and whys. A fun, quick read with no need to read the earlier ones in the series if you are new to China Bayles.
