Renowned archaeologist Dr. Elena Rivera makes a find that will permanently alter her life right in the middle of Eldoria, a modern city: an ancient obsidian amulet with mysterious markings and great untapped power. Elena is dragged into a perilous journey deep into the hostile jungles of South America when enigmatic stranger Adrian Blackwood interrupts a gala in her honor and claims the amulet is the key to unlocking a portal to a hidden civilization. Elena must negotiate treachery, changing loyalties, and the secrets of her own heart as old predictions come true and magical powers awaken. Elena is caught between her developing affections for Adrian and her instincts to guard the planet from the turmoil the portal threatens to unleash as his evil goals collide with a predicted fate. Elena and Adrian confront a climax in a secret temple covered in mist that will test everything they believed they understood about themselves—and each other. Ancient forces have to face their strongest anxieties if they are to seal the portal and protect the future since the fate of both worlds rests on their stirring action. Some doors, however, once opened cannot be really closed.
