Review Detail of InHisName in King's Awakening

Holy. This is a story about an absolute idiot. He fully believes serving 3 years in maximum security prison, and being framed as a terrorist by his leadership is all part of his grand mission. To his utter surprise after 3 years half his family is dead, his name is tarnished and his little sister is about to trafficked into a prostitution ring. Even still, he's apparently the 'invincible lord' who is the height of personal power and supreme intelligence in the world. What kind of plot is this? What kind of protagonist is this?
