This is van Daniken's latest (2020) contribution to the world of ancient astronauts.
Sadly, the war of the gods gets short-changed as he once again re-hashes, saving until the last 32 pages, information about his latest escapade. In Chapter two, there is some speculation as to the "wars" of the gods, but it gets shortchanged. Is there a certain sameness to his more recent books where you get the feeling you've read all this before? Indeed there is because a lot of it is material which is re-hashed from earlier works. Presumably, by including that material again, he can at least reach close to 200 pages which he almost does this time (198 pages).
If you're an avid van Daniken reader, you have to have this, of course. If you're someone who has seen Ancient Aliens on the History Channel and want to learn more about the subject, buy some of his earlier works, beginning with his first, Chariots Of The Gods and work your way forward from there. At some point, you'll be saying to yourself "I've read all this before" and you can quit.
For the die-hard van Daniken fan - not for the newcomer to the ancient astronaut theories.
