Conspiracy theories and secret histories are always a rich source for excellent and innovative stories. The tricky part lies in the execution. Which is what is lacking here. Everything feels rushed and there isn't any grand scheme or struggle. In its eagerness to touch upon various historical events and theorize them on its own, the story suffers from lack of depth. So far 20 books have been published in English and after about 6, I find no reason to continue. There might be a chance of this getting more focused later on, but I highly doubt it.
