Well, this went the same as the previous books and it was as annoying. Nothing happening till 60% beside pure frustration and then things moved and it got enjoyable and entertaining. I still liked the thought provocation but previously I regretted to have started the series.
Thankfully I am now done and we can move on and never think about it much again.

On a side note, Rowan was my favorite character and he just got ruined in this book. Thank you for that.
