This book was extremely exciting and came up with some brilliant photos and drawings. The author features the mysterious Moon, so many puzzles, its mysterious structures, the crack, signs and monuments... is there someone else on the Moon? Then tDavid has a look on the Mars and the search for life on this planet (lines, faces, pyramids). Later on he speaks about mysteries on Venus and Mercury. Were there ancient space bases on the outer Moon? Everyone interested in all those speculations should have a look into this book. The author sums up all kind of fantastic theories in his book and tries to find evidence for alternative science. I was absolutely taken by the book, the jaw dropping photos and its spectacular insight. Highly recommended!
