Vanished Moon could almost be read standalone rather than a tumultuous end to a trilogy. New ideas blossom in to central themes with strands from the previous two entries becoming almost background story and plausibility is stretched somewhat with the time-travelling McGuffin, which removes any predictability at the cost of suspension of disbelief. Such weaknesses are absorbed by the strengths of the narrative, it's engaging characters and the epic scale of the trilogy. Entertaining from start to finish, the story of Mina and her One God is riveting stuff. It could have been great, however it is still good enough.
