Exquisite, cozy, at times funny, at times sad, and unforgettable. I won’t bore readers with another summary of the story; they’re abundant on this site. I will say that with Isabel Archer, James earns his place in the canon with a proto-feminist (yes, I said it, proto-feminist) novel of a remarkable, if hard to describe heroine, who is faithful to her idea(l)s, rejects the affections of strong (but good) men, and suffers unnecessarily at the hands of a Machiavellian cad and an equally manipulative woman.
If you don’t like long novels—avoid this one like a plague. If you don’t like novels written in style from another era, get thee hence! If wordy, complicated sentences are anathema to you, you’ve probably already stopped reading this mini-review.
If I were to advise a reader at all, I’d suggest reading it in as short a period as you can. Bite the bullet, finish it off keeping as much in mind as you can. I’d also advise reading it on a Kindle (for the built-in dictionary) or, at the very least, keep a dictionary at hand. I hope you enjoy it as much as I have; and if you don’t—if you read the wrong book for you (this one), please, please, don’t say James is an idiot (or some equivalent) or that the book is just boring (or some equivalent)—instead, face the fact, you read the wrong book.
