Quite an adventure. Jake Bento with two companions ( one an Amazon warrior woman from the Sea of Grass, which is present-day Ukraine, the other, an African-American soldier who was lost on a mission into Laos) goes back in time to the Bronze Age to find out what happened to previous missions, which inexplicably disappeared. Garcia y Robertson really brings the ancient world to life and adds fantastic elements. Jake finds Atlantis but that's not so fantastic. It's the island of Thera, which was almost totally blown up in one of the greatest volcanic eruptions in history ( today, it's the island of Santorini and one of the most beautiful places in the world to visit--I've been there twice). More fantastic is Jake and his buddies coming across the mighty Hercules... and other gods and goddesses, not to mention various mythical creatures...
A good read, published in 1997, it is the sequel to "The Virgin and the Dinosaur," which introduced Jake and other characters. I didn't read it but I would like to get the book sometime to read.
