Read: The Tower
Now, with the third installment of Toyne's Sancti trilogy, things take a strange, unexpected turn. What started as a religious thriller, an esoteric, cabalistic piece of pulp fiction, has turned almost into a science thriller. The religious characters are reduced to nut jobs.
The origin of the story is perfectly obscure and the new character's plot line is quite dominant, and indeed even more interesting than what happens to and with the old protagonists. Yet, to the original story this new plot line adds nothing, or very little. Rather, it subtracts from it. The concept of the first (oppressed) tribe is diluted, reduced to a free mason lodge. Toyne drifts away from his original idea.
Hence, despite being an entertaining novel The Tower shows that Toyne is not capable of staying within the confines of his own fictional world and produce an internally consistent piece of fiction. Resorting to over-used tropes isn't a good sign either.
