Heroes of the Empire - The Unari Empire Trilogy, #3

The world is falling apart around Aton Askins. His childhood friend is rotting in a cell for a crime she didn't commit. There are soldiers in the streets of Cye and an army of angry widows waiting outside the city. His mystery employer might be using him to gather artifacts of the ancient gods to build some kind of weapon. Now he's been given one last job, one last artifact to find, supposedly on a mythical floating island halfway around the world.
He needs to stay in Cye to help his friend, but he needs to finish his work so he has the money to take his family away from the city. Most of all, he needs to keep those he loves safe from what's coming. The Widows Army is restless and may be slipping away from Belwyn of Annanais. Stuck outside of Cye, unsure of what to do next, she needs to do something, anything, to make sure the promise she made to these women to find answers about their loved ones doesn't go unmet.
When an unlikely ally presents himself, she uses the opportunity to enter the city and finally find the evidence she needs to show the world the truth of the Port Ambs bombing. All the while, the currents of protestors and revolutionaries are threatening to overtake her. Lives collide and the fate of an empire hangs in the balance in this thrilling conclusion to the Unari Empire Trilogy.
