The Two-Faced Queen by Nick Martell

Michael Kingman thought he was going to die by the executioner’s axe, forever labeled as a traitor. Still alive, and under the protection of the Orbis Mercenary company, Michael and his family and friends are deeply involved in the seemingly rival conspiracies that are tearing The Hollows apart. With the death of the King, both the Corrupt Prince and his sister Serena are vying for the throne, while the Rebel Emperor is spreading lies amongst the people, and all of them want Michael dead. This is a story of betrayal, murder, and rebellion, and in this direct sequel to the debut novel The Kingdom of Liars, also some hope for justice.
