I was rather curious when making this point known in Act VII if readers would spot a little questionable circumstance later on. As many readers of the series know, Doku's sister is the chieftess of Red Peak and ruler of the harpies in Koskaysil. No name has been given, however she's most certainly on the to-visit list for Daniel Sorres very soon.
However, isn't it rather odd though, about Shadow's Refuge? A sanctuary that is run by a human man, that welcomes both humans and monsters alike as residents, that is located right at the base of Red Peak and even has harpies working as nurses within its peaceful walls. A very good example of humans and monsters coexisting, at least to a certain extent. And yet, Doku has never mentioned it once to Daniel. Wouldn't that be something she would be rather inclined to inform him about? Why not mention it at all?
It won't take long before this mystery is unraveled, but I invite readers to speculate as to why Doku hasn't informed her mate about such a place in all her time with him.
