Endgame: The Calling by James Frey

In Endgame: The Calling there are twelve protagonists and antagonists:

Sarah Alopay 

Jago Tlaloc

Aisling Kopp

Hilal ibn Isa al-Salt 

Maccabee Adlai

Baitsakhan

An Liu

Shari Chopra

Marcus Loxias Megalos

Kala Mozami

Alice Ulapala

Chiyoko Takeda

Each of these people are Playing a cruel game played on humanity by The Gods. Each of these people are Playing for themselves. Kill or be killed. They are protagonists and antagonists at the same time.

My favorite protagonist/antagonist Chiyoko Takeda is from Japan. She has dark black, straight hair with a low fringe, ivory skin,long, black thick eyelashes and full, dark red lips. She looks like an average Japanese schoolgirl apart from her eyes. They are filled with confidence, fury, and something deadly. She is a feisty, confident, and skilled assassin. She is cannot speak or produce any sounds with her mouth. She is silent and deadly. Both her parents died when she was young, so she lives with her caring Uncle who loves her even with her disability. She has trained since she could walk, to fight, deceive, survive on limited resources, infiltrate, hide,and eventually become the tribe Mu's Player for Endgame.
