There are so many layers of deception and betrayal in the book, and many twists and turns. I liked the cleverness of the story, and I appreciate McEwan's writing. I liked that it is a 'literary' novel, with lots of references to books and authors, to the relationship between writer and reader. Snippets of Tom Haley's short stories are included too, 'stories within the story.' No spoilers, but the book is worth reading for the last chapter alone.
