Here is my BL novel:
This novel is meant for mature audiences since it has many mature themes:
Roenan wakes up (gravely injured) after his own mother attempts to kill him. When he comes-to after blacking out from his injuries, he realizes he’s been taking to the enemy country of Vernajja during a time of war. He quickly befriends a fellow prisoner of war from his home country of Jaeda, as well a Vernajjian soldier who seems keen on helping him. As his friendships with the two grow, Roenan begins to feel something deeper with his enemy.
While abiding by what is expected of him at the enemy camp, he begins to realize that there is something big the Vernajjians need from him. In his attempts to understand what they need and what he should expect out of his future, he begins to question everything he thought he knew about his past.
This novel focuses a lot on the relationships between the characters along with the subplot.
