Knight of the Demon Queen

Jenny is broken from what happened in the last book, John is under sentence of death because of his dealings with the Demon Realm and now he has to fulfil a promise to the Demon Queen to go on a quest and enter a realm that is so far out of his reality that I'm surprised his head didn't almost explode from cognitive dissonance. He basically ends up dealing with an almost real world but worse cyberpunk future for what was then with legends of magic but living in it is a grind.
It's a bleak book, apparently written when the author was in a bleak mood. Thankfully it wasn't the last in the series.

A depressed, powerless Jenny Waynest and her husband, Lord John Aversin, are blackmailed by the Demon Queen Aohila into a quest through dangerous hells to capture a renegade soul.

Jenny struggles with the loss of her magic and the mental lingering of the demon Amayon, causing immense grief and isolation. To save his family and land from plague, Lord John Aversin agrees to serve Aohila, leading him through horrifying, alien realms.

While John travels through hells, Jenny must face her own battles in the Winterlands, ultimately trying to protect her son, Ian, and encountering the dragon Morkeleb.

The series has picked up drama, but the story gets lost in repetition, confusion, and gore. Either it is not the end of the series, or it breaks Lady Bracknell's rule.
