Well, "wicked" is not the word I would use to describe the witches in this series. This is the second in the series, and as I have read the first two back to back, I can honestly say the second is an improvement over the first. The bickering between the family members is down, and the writing is smoother. There are still problems with the editing though--tense changes with verbs, sometimes some confusing sentence and paragraph structure, but those are fewer than in the first book.
Again, the author captures the small town feel pretty well which I think is a good thing. Those people from small towns will appreciate that. The pop culture references which vexed me so have been cut down dramatically from the first book, and are used in more appropriate places, so no problems there. Overall, it's a smoother read, which shows the author gaining experience, yay for experience!
The characters though... I just really... really... hate the main characters. The women still all sound the same to me; individual character voices are impossible to pick out. They are also still very argumentative, although that has been lessened from the first book. (Or perhaps I'm used to it now?) There was also more magic this time around, though still pretty... in the background. Just the characters. It's hard to read a series where you don't like the main characters, and they are downright mean to each other. Maybe because it's in text and not in a visual medium where you can pick up body language clues, but all of the barbs for each other seem meant, not kidding around, but honest-to-gosh meant in a malicious way. I'm sure that's not the intent, but that's how I'm reading it--again, text is not a visual medium, so some clues one would pick up on are just not there. Of the characters, Edith, the ghost, I think is my favorite.
Overall, it's a light read, and maybe (as the author puts in disclaimers) the style of the writing is not for me. It's not bad, but not terrible either.
