Volume 16 directly continues an arc started in volume 15 and has several major developments that depend heavily on prior events. This is not the place to start reading – go back to the beginning.
The entirety of this volume is devoted to the remaining chapters of The Lamentation of the Earth (parts 2-7). Last volume had a lot of heavy revelations, but Yagi is far from done with the surprises. Clare’s conversation with an “old friend” continues and portrays a intriguing tangle of complex loyalties and motivations, while filling Clare in on Riful’s machinations. Meanwhile Deneve and Helen encounter a terrifying new weapon of the Organization that made my skin crawl, leading to a dramatic change in the long running power struggle between the Organization and the Creatures of the Abyss.
Absolutely phenomenal stuff, with another fantastic ending hook for the next arc.
