Well, having enjoyed Blood Royal so much (I still can't get over the fact that Graeme awarded it 9.5 out of 10!) he didn't delay in picking up a copy of Dark Side. As you'll see from this review, he didn't enjoy it as much - but 8.5 out of 10 is still a very respectable score, if you ask me.
I particularly liked this part:
Green attacks the plot with his usual zest and vigour, giving us a story that rockets along with a mix of heady spectacle (I’m thinking of the giant robots here, loved that bit) and murderous intrigue. Mysteries abound and Quicksilver has to solve them all; the plot moves far too quickly for the reader to have any choice left but to come along for the ride and what a ride it is. There is plenty going on but Green has no trouble keeping everything in the air and ticking along nicely. And what a cliff-hanger ending!
