She then learns far more than she would like to know about these pyramids' secrets. Daria's life takes yet another turn when she discovers her capstone has the power to stop an impending planetary shift. She is caught between two difficult choices: Use the capstone to stop the shift, and unleash the evils that destroyed Atlantis. Or not use it, and allow the shift to wipe out half the world population. ...What would you decide?
