I didn't quite like this, but it's Wharton—the novel is interesting & unsettling. It seems like it takes the themes that were satirised in Twilight Sleep (irresponsible parents blown about by every wind) & gives it a darker turn. In this one we see the children as fully-fledged characters & the costs of bad parenting hit hard. The other thing is the character of Martin: predatory, genuine, or wayward Peter Pan? All very disturbing to think about.
