Perhaps, I kept thinking, this is Meg Wolitzer’s best novel yet. It’s a grand, sweeping story about a group of kids who meet at a summer camp in New England in the 1970s and what happens in their lives. There’s Ethan, talented but unattractive; Goodman, an unstable hunk, Jonah, who is gorgeous but damaged, the beautiful Ash, the hot Cathy. And then there’s Jules, our brilliant, perceptive narrator, a suburban girl who wants to be an actress but ends up as a therapist. Wolitzer hooks you into these people and their lives with smooth expertise, and moves them through several decades of American history.
