So far, my favorite of the MOTU series. I think I liked this one because there is some grounding in reality. The pyramids exist, Stonehenge exists, the Nazca glyphs exist. There's quite a bit of real history here before it veers off into la la land. To be completely honest, a lot of the wacko theories about these ancient monuments are pretty fun to read about and enough of the real facts are there to let you make up your own mind. Sadly, Shirley Temple does not play a role in solving any of the ancient mysteries.
