After the discovery of several crystal artifacts dating back 15,000 years (chronicled in CRYSTAL GIFT, the first book of the Crystal Skull Trilogy), and the realization of the true functions of the crystal skulls (chronicled in CRYSTAL GROTTO, the second book of the Crystal Skull Trilogy), an evil was accidentally unleashed upon the planet in this final chapter of the Crystal Skull Trilogy. Dennis and Susan Mathews, and Gary Benson gained access to the lost technologies of the long past advanced civilization of Atlantis. Dennis, Susan, and Gary feel safe until a new leader of the Tri-Lateral Consortium emerges to put the entire planet in jeopardy. With a final desperate plan, the Tri-Lateral Consortium moves to capture sole control of the ancient knowledge and emerge from the shadows to exert their control over the entire planet. The only hope to save humanity lies with Dennis, Susan, and Gary, with the help of Jake Roads. In a coordinated effort, Jake Roads leads Dennis, Susan, and Gary in a desperate plot to save the world from global dictatorial domination. With their lives and futures at risk, Dennis, Susan, and Gary follow Jake on a fast paced race to rid the planet of a long suppressed evil released from the depths of a knowledge matrix and drive the evil entity to a final CRYSTAL GRAVE (the newest and final book of the Crystal Skull Trilogy). Crystal Grave is the third and final book of a Crystal Skull Trilogy. This is a story of a conspiracy and race to discover an ancient power and save the world from a long lost evil. A legendary power revealed to be access to technologies far more advanced than anything seen on the planet for 15,000 years. Technologies accessed through the legendary crystal skulls.
