Making my way through the book, about 3/5ths through so far.
I am somewhat perplexed. Almost all of the issues I had from the early spoilers folks pointed out aren't addressed, mostly because they don't actually exist. The work seems to be in the broad strokes perfectly inline with Forgeworld.
The rest of the book is marvelous though and I am somewhat reminded of Wraight's usual habit of tricking readers into overlooking the flaws of PoVs if you are not careful to dissociate.
Most tellingly, this is a book that dwells heavily on doubt and fear. This is hardly new to 40k and especially with regards to the Emp's more 'purely monstrous' angle that alot of the fanbase is holding onto for dear life these days.
But thats the brilliant thing about this book really, if you take a step back from it almost every single PoV is almost clinically narcissistic and self-impressed in the extreme.
My favourite example is probably the one accusing the Emp of playing god while having cultivated a literal cult to herself.
Will post more when finished but so far it is already a marvelous book and I am glad as all hell I didn't let the spoilers turn me off.
