The Crystal Skulls

From author and History Hunter, Mark Greenwood, comes a new mystery about legendary crystal skulls.

Legendary crystal skulls made by ancient civilisations have been a source of controversy for decades. But are they more modern than we think?

Made by no known human process, the crystal skulls have defied investigations to determine who made them, when they were made, and what tools were used.

Could they be relics from the legendary lost island of Atlantis, or are these exotic artifacts an elaborate hoax?

The truth is out there.
