Nirvana in Fire Vol 2

No war is merciful, but even the battlefield doesn't offer the same treachery as the walls of the imperial palace. As the princes vie for power, anyone can become a bargaining chip-a commoner, an official, or even a princess from the southern borders. Mei Changsu must abandon his past friendship and risk others' destinies to protect his country from impending destruction. Is his decision driven by duty or his heart's desires?
