The compelling conclusion to The Lightning in the Collied Night and The Loss of What Is Past: In 22nd-century Aotearoa (New Zealand), Earth struggles to recover from the World War of 2057 while the world's chief physicist and her husband grapple with an immeasurable loss. When a seemingly unstoppable threat to Earth emerges, the M¿ori scientists must overcome their grief and decide whether to violate the most sacred values and beliefs of their people in a desperate attempt to prevent Armageddon. Although this novel is the conclusion to a trilogy, it was written to stand alone and thus can be read independently of the other two books. The five main characters and some secondary characters are M¿ori, the indigenous people of New Zealand-very rare for a sci-fi novel. This novel explores the culture, religion, and language of the M¿ori in a futuristic sci-fi setting.
