Wow. I never know how authors will build on a complete story, but luckily Green left things open at the end of the first book and that really works here. We get off to a bit of a cautious start, there’s quite a slow-burn feel to the book but when things start to happen, when the day comes, it comes with a bang. I found the whole final third of the book electrifying and unputdownable and far more satisfying as a conclusion than the end of the first book, which I also of course thoroughly enjoyed.
