Vengeance of hope - P. J. Berman

When the King of Bennvika dies in suspicious circumstances and a foreign usurper named Jostan seizes the throne, ruthlessly imposing his will on the population, a disunited triumvirate of leaders and their followers must attempt to resist him. The first is Silrith, the ousted philanthropic Princess who had been expected to take the throne. The second is Ezrina, a vengeful rebel desperate to overturn years of ethnic oppression of her people, the Hentani. The third is Zethun, a minor noble who believes the only way to fight for the common people is to abolish the monarchy altogether. As the various factions fight the threat of tyranny and religious persecution, each must be prepared to make the ultimate sacrifice for their cause.
