The monster that is the 20 Palaces series got cancelled.
Now, and spoilers apply, but the book series is brilliant. And one of the spectacularly brilliant things it does is not bore you with the back-story and instead allude to it through the course of the stories themselves.
It's certainly not true for me. That's why with trepidation I'm ordering the prequel.
But I'm gonna do it.
Harry Connolly is the author. And although I was digging the very organic way that the back-story was revealed, I'll bet the prequel works. And besides, I think the books should become a TV series. But, you know, I think a lot of things.
