I loved Nick Harkaway's first book, the Gone Away World . I also support authors writing more challenging books and am impressed with what he's achieved in writing this mind-expanding futuristic detective novel. However I found the book took me several weeks to finish. If you enjoy near future science fiction/fantasy/dystopia that will challenge your mind and tickle your brain, give this a try, but if you're looking for an easy read it won't be your cup of tea. Memorable characters include the ultimate Detective and a planet mind.
