The Final Summit: A Quest to Find the One Principle That Will Save Humanity, an interesting plot with a pretty decent storyline to boot. If we could save humanity just by solving a puzzle and go back into time; I think we'd be a lot more successful then we are now. The author really indulges into the book and really shows us humanity. It's quite an interesting book and I do recommend it. I'm not really sure what else I can say about it. I know it's not 200 words but I don't really know what detail I can get into other than it did have some minor holes, but they were so slight. The book itself is good so check it out!
