It was with some trepidation that I picked up Mark Chadbourne's The Queen of Sinister (book two of The Dark Age), mainly since I found out that I misread Goodreads' listings, since evidently the third trilogy was written after the second, not mixed the way I thought. (To be fair, they're bibliography of him is all screwed up.)
Anyway, I needn't have worried, since the first book of the 3rd trilogy really doesn't give away much of the plot of the second, focused on the past the way it is. This is not to say a brief passage in this one doesn't play a part in that book, but....
The Queen of Sinister follows around Caitlin Shepherd, who's village is hit by the plague. Being a nurse, Caitlin is in the heart of it, trying to provide palliative care to the dying. Which also means she's ignoring both her husband and child. Who aren't happy about it. Caitlin has a friend, Mary, whom I think showed up in the first trilogy, but I could be wrong. Mary's a retired psychiatric nurse and witch.
Since there wouldn't be much of a plot here without it, Mary does a seeing for Caitlin, and whatever comes through names Caitlin a Sister of Dragons. After Caitlin gets home, she finds her husband and son plague ridden and dying. Understandably upset, she goes slightly mad, waking up on their graves to a crow pecking at her.
In the mean time, Mary gets a visit from Crowther, who bears a mask that once belonged to the Mad God. Who was told to lead Caitlin to the Summerlands to find the cure for the plague. Which he does, eventually, after picking up Mahalia and Carlton and Matt. Mahalia and Carlton are a package deal, although Carlton is mute. Mostly. Matt is looking to cross to find the Grey Lands and his dead family.
They're also being pursued by what they know as the Whisperers, but what the Tuatha de Dannon refer to as the Lament Brood.
Not long before they cross, it comes out that Caitlin is not alone in her head. Four other personalities are in there, including one whom the others fear and keep from surfacing. About the midpoint, we find out about her.
Mary, in the mean time, takes on a quest of her own to help Caitlin from the Fixed Lands, all while being pursued by the Jigsaw Man. Which leads her to the find The God, who in turn asks her to find the missing Goddess.
Caitlin's party winds up first in Lugh's court (Lugh remaining neutral in the current conflicts) where they meet Jack (not church, but Jack), who spent time in the Court of the Final Word. Given the Lament Brood surrounds the court, Lugh threatens to turn the crew over to them, which in turn leads to the escaping.
As the journey to the House of Pain, and as Mary looks to find and return the Goddess, much happens. Carlton dies, which somehow drops Caitlin in Birmingham. Wherein she meets Thackary and Harvey. The former ends up getting kidnapped by the local Negan, who has a captive Formori. Caitlin finds him, find the Formori, and lets out the final personality, whom we find out is actually the Morrigan.
It's a long quest, but eventually everyone winds up at the House of Pain, except Mary, who does indeed find and bring back the goddess after more than a few misadventures. (I will say his recitation of all of the aspects of the Gorgon is amusing.)
There's a heck of a lot of symbology thrown in here, some of which I remember in the book I read out of order, like the Void in the House of Pain. More than a few characters make the "wrong" decision at the wrong time, although all of the external entities keep saying all choices are part of a greater plan.
I will also add in here that, since most of the plot lines center around the feminine, it also centers around what some groups would consider "the Female Mysteries". Which, I imagine each reader would be inclined to make up their own mind as to whether or not the male author portrayed correctly.
Honestly, it's a good read, even if the timeline is a bit confusing quite often.
