A dark space opera unfolds in the shadow of a crumbling multi-species empire driven by a nihilistic quest for power. The central palace of Crysth is overrun; the empire has surrendered to an invading army led by Wilhelmina Ming, a traitor from its own capital city. But the invader's power source is its god—a being they worship but can no longer control after the loss of their high priest in battle. Now, both the invader and the invaded are trapped inside the palace with no way to rein in the eldritch force that has taken over—and no choice but to join together against it. Ming's last hope is Speaker, the slain emperor's twin and former imperial steward who is somehow bonded with the deity. A wannabe artist and writer, Speaker has been held hostage for months, forced to recount the final days of the empire in the hopes that something in these details might give a clue as to the god's desires and motives. The Emperor's Twin weaves a gripping tale of hidden truths and political intrigue, unraveling the threads of an empire’s downfall and revealing the key to confronting the malevolent force that threatens them all.
