There are about 5 main characters, even though there are 12 lines these characters are focused on the most
- Sarah: Sarah is from the Cohakian line. She is smart, cunning, and will do whatever it takes to stop Endgame
- Jago: Jago is from the Olmec line and before Endgame started, he decided to team up with Sarah. Jago is very strong, and one of the best fighters out of the twelve players.
- An: An is the deadliest player in Endgame. An doesn't care who lives or dies, he just kills. An is playing for the Shang line, who almost killed him in his training
- Chiyoko: Chiyoko is playing for the Mu line, the most ancient of all the lines. Chiyoko is mute, which means she cannot speak. She is sneaky in fights, using small darts and other weapons.
- Aisling: Aidling is the oldest player, and when Endgame arrived, there was 6 days until she aged out, which meant she would no longer be eligible for Endgame. Aisling plays for the Celts, and she specializes using a sniper rifile
Endgame is a lot like The Hunger Games. There are 12 'players' that have no choice but to play endgame just like the 12 candidates have no choice to fight him The Hunger Games. Both books make the players/candidates fight to the death for the safety of their people. I would recommend the Endgame series to anyone who enjoyed The Hunger Games or any book like it.
