Seanan McGuire‘s fifteenth October Daye novel is completely centered on the protagonist’s wedding. Despite not actually being short, it feels short both due to everything taking place in one location and because the story itself is episodic. If it weren’t for the fact that this event is pretty important to the overall plotline I would’ve said it was merely a transitional novel (similar to the Unkindest Tide).
The twelfth TenSura novel meanwhile is basically a repeat of Book 6 without any of the action. Also with a 1-year timeskip and an abrupt ending. On the positive side of things they don’t dwell too much on the Labyrinth RPG aspects and it appears as though the next book will have quite a bit of movement with the whole start of the East vs. West war. Then again, there are apparently six more books already published in this series so I can’t rule out additional volumes of nothing but preparation (and if that’s the case for the next entry I’ll probably just drop the series).
