Just some thoughts:
... in a lake ? I can't imagine a tsunami would be geographically possible there. Not even if it came from the ocean. The wave hits near the beach and rolls inland after that. Aren't there mountains in between? The lake itself is big but not big enough that a wave could become that high. Except maybe if someone used a lot of water magic....
OK, let's say there is a huge wave. I would think the island can protect itself. Also the important parts seem to be high up or deep down below the surface.
Well given that we are dealing with a series about magic, I’d imagine there are myriad ways a powerful being could use this to their advantage.
But if I were an evil, unimaginably powerful being & I wanted to attack Demonreach, I would take a page out of @Mira’s book & use a combination of earthquake & tsunami as my opening salvo. Perhaps something like this will set off the BAT?
She is weak because it was summer or not yet winter at that time, wasn't it?
I think the old age symptoms come from the mothers' mantles. Somehow this seems to be the prize for that much power. A balance thing. Everything in Fairie seems to be about balance.
Or maybe Mother Summer is keeping her this way as long as the table is in Summer's hands and she has more power. To keep Winter in check. So that she would not overpower all the mighty ones in the world and take over.
Just like why there are counterparts to the Winter Queen and Lady.
Maybe that's why they live together.
CD occurs around Halloween which is when Winter is more powerful. In CD Mother Summer explicitly says “she rarely leaves our cottage anymore, she lost her walking stick you see....it’s painful for her to travel, even briefly”.
The question is, why? As Bob says, the Queens are true immortals.
Idea about Sanya:
Maybe to show, that to be a Knight of the Cross you don't have to be the perfect hero type like Michael. You can be clumsy. And you can even be agnostic
Possible, although then I expect Butters to be even clumsier over the next few books. It seems weird though that JB goes out of his way to talk about Harry’s leg being cut in SmF only to go nowhere with it.
As good as Changes is as a narrative, in it, Harry can best be described as a d**k. He's selfish, childish, and generally speaking, unhinged. Ghost Story seems to want to explain that behavior. The answer it appears, is the devil made me do it. That's the Cliff's Notes version.
True but again, this could be covered more easily in a short story than a full case file. I mean having ghost Corpsetaker & Evil Bob as the bad guys... especially after Changes seemed like a let down.
I get that JB wanted to introduce us to new-ish concepts like ghosts/ lemours/ shades etc., but I wonder why he recycled a couple of side- bad guys from the previous books & made them the big bad of this novel. I mean what happened to Grevane’s ghost?
This could have been an interesting book to revisit the ‘ghosts’ of Harry’s past & all the people who’ve died in Chicago - like Sells, Kim Delaney, Shiro etc. By the amount of time that was spent developing Fitz as a character, I’m sure we’ll see more of him in the later books although I found him to be uninteresting.
I dunno, it was kind of a lackluster book, but that’s probably because the books leading up to & after it (TC, Changes, CD, SG) are some of the best in the series.
