Well, Jon Green's been getting a bit of love from the internet, it seems. Here are two very decent reviews of his books from webland...
Graeme Flory, over at Graeme's Fantasy Book Review, is always a big fan of Abaddon's Steampunk Laureate, in this case awarding Blood Royal an awesome 9-and-a-half out of 10:
"What you get as a result is a plot that moves at a frantic pace whilst making complete and utter sense... Blood Royal has it all going on and at such a speed that you are almost physically compelled to keep reading."
Pablocheesecake, over at The Eloquent Page - another reliable Ulysses-fan - was similarly effusive about Dark Side:
Dark Side joins the existing novels as a worthy addition. Green has crafted yet another action packed rip-snorter. Each new release fleshes out the Ulysees Quicksilver universe and is a guaranteed must read. Long may the adventures of Ulysees Quicksilver continue.
So that's good.
