I had fun reading this book. Mieville has fun with the language and with conspiracy theories, and you have to pay attention or you'll become hopelessly lost. And even if you do pay attention, you might have to come up for air occasionally and take your bearings.
The style and climax of the book are reminiscent of Umberto Eco's Foucault's Pendulum - self-engendering conspiracies and self-fulfilling prophecies - with a Cthulhu-like twist. And as a bonus there's a Trek-obsessed teleporter and a working phaser.
The final observation I'll make is that Mieville has also created one of the most disturbing psychotic killer in the character of Goss and Subby (and you'll understand why I use the singular if you read the book).
Very highly recommended to Mieville fans and those urban fantasists.
