The chamber was just the beginning. Six months after uncovering an impossible secret beneath Utah's Uinta Mountains, Professor Ammon Lundquist and non-binary park ranger Aspen Rhoades thought the danger was behind them. They were wrong. A hidden message in his ancestor's locket reveals a shadow archive containing the location of something far more significant: the First Temple, a repository of knowledge from a civilization that predates recorded history by thousands of years. But Ammon isn't the only one searching. Enemies on Every Side The Consortium may have fallen, but its shadow reaches from behind prison walls. A new ally with impeccable academic credentials has joined the team-but in this world, trust is a luxury that can get you killed. And within the Vatican, factions are moving: some who want to control the ancient knowledge, others who believe it must be destroyed at any cost. What Would You Sacrifice to Protect the Truth? With their team scattered and hunted, Ammon must confront an impossible choice. The First Temple holds knowledge that could transform human understanding-medical breakthroughs, astronomical insights, technologies beyond modern comprehension. But it also contains secrets that powerful people will kill to possess. Some fires warm. Some fires destroy. And some knowledge, once released, can never be contained again.
