Probably more than any book I've read in the past couple of years, The Interestings made me think about what I like in a novel. There is, in terms of mechanics, a lot to admire here. The sentences flow well, the writer has a command of the subject matter, and has sympathy for the most of the main characters she creates. Meg Wolitzer is a pro at what she does.
But then there are the subjects being addressed, the characters, and the tone. Personally, I can't connect to the people described here. I'm not an East Coaster. I'm not super-liberal. I'm not plugged into popular culture, even the stuff that is regarded as high-brow television. If you're a boomer who loves things like The Daily Show, reads the Style section of the NY Times, and reads profiles in the New Yorker of movers and shakers in the business and art world, you'll probably find The Interestings appealing.
Wolitzer has written a sprawling, decades-long tale of six East Coast kids who grew up in the 1970s. Five of the kids come from wealthy homes full of strivers. The sixth is the main character in this novel and is a scholarship kid enamored of the privilege of the others. In a lot of ways, The Interestings is a much better version of another novel I read recently, The Marriage Plot. They are both Jane Austen-like in their approach. Both have third person narrators who are not at all shy about telling exactly what is going on inside the heads of the principal characters. Mental illness plays a significant role in both stories. In The Interestings there is the welcome bonus of some quiet, droll humor.
If you like traditional novels in a modern setting that are focused on relationships between friends, The Interestings will likely be a worthwhile read. If you have an aversion to East Coast culture and gravitate toward novels with big ideas, I'd stay away.
