I have it and I'm just over halfway through. I generally don't go in for genre fiction, but this one is pretty brutal. Bill designs great games but his writing leaves much to be desired.
The novel jumps around to various groups of characters while not doing much to establish or build any of them. Consequently the story feels seriously disjointed and it really struggles to hold interest. It's just a case of too many characters doing too many things.
There are also numerous instances of cringe dialogue, some of it is cheesy in the fantasy heroic sense, and other times is just jarring. 'Here comes a Infernal Armor Animus!' / 'I have great perception' / etc.
It's not completely awful, but it has plenty of flaws.
