I received a review copy of this book.
Often times, labels placed on books makes or breaks a book. In this case though, I have no idea what historical progression fantasy even means. So far as I can tell, there's nothing historical about this book. The fantasy works for sure, but otherwise, I just don't get the reference to progression other than that the main character is able to handle more and more simultaneous pieces of information at a time, so I'm not sure it qualifies as LitRPG, but progression? Well, maybe. Simple changes in the story could place it clearly in the LitRPG genre, but clearly that's not what the author was aiming for, so friends, I have no idea how to classify this story. On the other hand, the story isn't bad, and perhaps this setup of the world will migrate to something more indepth in later books, but for what it's worth, the story is good, and while it does read like a LitRPG story with the LitRPG elements removed, it's still worth the read if you like magic and fantasy worlds. It's interesting on those aspects alone, add in the almost LitRPG pieces, and the story becomes enjoyable on a whole new level.
Secrets abound in this story where the gods take direct action in the world, although it's generally frowned upon we're told, and having multiple gods combine to help a single individual has never happened before. That too is part of what makes this story interesting.
In any case, if you like fantasy, magic, impossible feats that hide their complexity, then this story might be one you want to add to your to read shelf.
