This review is for readers who are unfamiliar with Neal Asher's work because...let's face it. If you're already a fan of his work, you're not reading this review because you're already reading the book! And when you're done you'll be all disappointed because you now have to wait for the next one.
So for readers who have not read any of Asher's work before, I have to say...Don't buy this book. Wait! What? Sorry, but while this book is great, it's not the book you want to start with. Technically, you can, as it's not *really* a sequel, but the events in this book take place after events in previous books and many characters from previous books are referenced. And more to the point...this book ties together many loose ends, so if you read this book and like it (which you will), you'll want to go back and read his earlier books. And you'll be missing out a lot since this book is somewhat "spoilerific".
So stop here and go read his earlier Polity books. Specifically, the "Cormac" series, starting with Gridlinked. [...]
You won't be sorry.
And when you're done with those (and this book), pick up the "SpatterJay" series. And then his stand-alone's. And then the short story collections. And then re-read them all again, while marveling at the universe he has created. And then wait anxiously and impatiently for his next book.
But when you've become a raving Neal Asher fan, don't blame me because remember...I told you not to buy the book.
