With apologies, this here is a hit and run criticism - the only reason I think it's still worth posting is because it's about first impressions.
I've just read the prologue and most of the first chapter - and I'm hooked

The thing is when you start reading, you're not hooked, so you're much more critical. With that in mind, my criticism is aimed mainly at the prologue. Note that incidences do seem to reduce after that anyway.
Excessive use of comma's was the thing that disrupted my reading most (and that mainly in prologue): I'm no grammatical expert, so your use of commas may be technically correct - but I found a few examples in the prologue where, if I read the text out loud, it would sound quite stilted. Maybe I read different to others, but I find I notice that
without actually reading it out loud, and it distracts me from the content.
All my opinion and FWIW!
Where I remove something below, I put empty square brackets []
