He has very positive things to say about Unnatural History and Human Nature but clearly loved Leviathan Rising.
Here are a couple of my favourite bits from the review:
On Unnatural History: "Throughout this work the author amuses with alternate tech, such as Ulysses Quicksilver's personal communicator; a brass and leather mobile phone, an Overground train network in Londinium Maximus, mechanical bobbies, and Beefeater-drones with clockwork craniums."
On Leviathan Rising: "...the real star here is the story behind the man-made Kraken. This has been well thought out, and has a terrific pay off. Leviathan Rising was, for me, streets ahead of its predecessor in terms of storytelling, and was just about perfectly paced."
On Human Nature: "From this point the story rattles along like a British Rail train with imminent brake failure, incorporating a desperate industrialist trying to escape the prison of his disease-riddled body, and a mad German vivisectionist. Some of what is portrayed is on the vomit-inducing side of gruesome, but definitely serves to keep attention glued to the page."
And on Vanishing Point (the novella that appears at the back of Leviathan Rising): "The best of these is... "Vanishing Point" which shows what the author is capable of when he allows himself to write more tightly, and with a sharper clarity of focus."
