The Testaments was released in September and I've just finished reading it. It nicely ties up a lot of questions remaining after The Handmaid's Tale. It also tells the story of the downfall of Gilead. And the story of Offred, including her real name.
If you are a lover of Margaret Atwood, you really want to read this book.
If you are a non-fan, which I just can't understand, read it anyway for closure.
