Having read the first book (and seen the movie), I'm disappointed in this sequel. Putting aside my feelings on the characters and their adventures in the first novel, this book on its own has a very weak "plot" and a poor structure.
Once upon a time, Alex, Jane and Sukie were best friends living in a small town in Rhode Island, dabbling both in sorcery and seduction of their neighbours. Thirty years on, they have gone their separate ways, found love and subsequently lost it, which leads to their current position as the titular Widows. Unfortunately, the introduction to the entire story (and a rather large chunk of it) is spent following first Alex, then Alex and Jane, and finally the entire trio, as they traipse around various world locales listening to (and forcing the reader to endure) history lessons about foreign cultures. Most of this part of the story read like a lecture; I might have enjoyed it more if I had purchased a book called The Encyclopedia of Eastwick. The real shame in this is that the examination of history and culture dwarfs the relationships of the women; a casual phone call after nearly three decades, presented as a rather distant ten-minute conversation, leads to an almost immediate rekindling of friendship and an agreement to travel the world together.
There is little emotional depth behind the reasons these women want to resume their friendship, and this sense of unease amongst them pervades the entire book. This was a lacking on behalf of the characters in the first novel which seems to have grown even worse here, in that they are so jealous and petty and vicious - even with one another - that you sometimes wonder why they are friends at all. The answer seems to be that they, as witches, are snobs. They would rather their trio, bitter as it is, than the morally upright and therefore common people by whom they are surrounded. Not all friendships can be perfect, but the glue which held these women together in Witches - which, they underline here, involved their shared gripes about children and schoolteachers, local gossips, the banality of Eastwick and the puritanical townspeople - is gone in Widows. I would not want to read about three people who don't like one another very much travelling the world together any more than I would care to actually travel with them.
The book reads, overall, as though Updike wanted to revisit the world of Eastwick but did not quite know how to do it, which is where the structure seems so strange. After much of the story is spent watching the widows flit from place to place, ruminating on their former lives and how every crease, odor, lump, bruise and wrinkle has turned them into shadows of their former selves, there is a sudden (and almost unexpected) introduction of some danger for the women in the form of a character from the first book who returns intent on getting revenge. However, it is hard to care much about any of the womens' fates when they seem to care about one another's so little. Overall, the book reads like a series of small adventures - first, into the travels of the three main characters, and then into their attempts to each repair some wrong they feel they have caused in the lives of those around them. The attempts to tie this all together with the return of the dangerous character seems almost like an afterthought.
With regards to prose, Widows works very well in some places and suffers in many others; there are sentences and passages which are overlong and complicated. The characters have a bad habit of all speaking in the same voice, uttering run-on sentences designed to give the reader backstory but making them all sound like they are reading from the same expository text.
Mostly an examination on how much getting old sucks, there is very little to enjoy in revisiting the world of the witches of Eastwick. Anyone who has read the first book may well be disappointed by this sequel, and anyone picking this up having only seen the film will find almost nothing familiar about their adventures - or any fun.
