I've already forgotten the name of the protagonist, but the gist is: prominent noble in standard fare fantasy world is jailed for killing his wife. Son doesn't know what happened, but vows to get father out of jail except he's first being sent to the front lines of an unwinnable war. He draws up plans like a Pepe Silvia meme, wins the war in hours, then high-tails it back to the homeland for poorly written Machiavellian political intrigue to get his dad out of jail. Dad is mad at getting out, confesses to killing wife because she nagged, and then father & son are on opposite sides of more political intrigue.

Poor poor execution on a half-assed idea.
