A brilliant expansion of the previous books themes and plot, with some fantastic new additions. Thoroughly entertaining high-concept space opera. It's fun to think about trying to explain this book to someone who has never read science fiction.

The only criticism you could make is that the section where the original crew land on Nod and slowly discover what is happening there is one of the most thrilling and thought-provoking pieces of sci-fi horror ever written. Even though the rest is still great, it’s impossible for any book to match the perfection of that section.
