Tiamat is beautiful, rich, and the kind to never let anyone walk all over her. She leads a life where nothing is forbidden to her... Well, almost nothing. To maintain the privilège of remaining on Earth and delay the fateful moment when she will become the ruler of Hell, she must keep her double life a secret and not make waves... But above all, she must regularly pay the price her father, Lucifer, imposés on her. For centuries, she has bowed to these constraints, but an event will put an end to her dream life... Unless, this time, she succeeds in bringing her father something more precious than those she was able to obtain for him before, and at the same time satisfy her father's wish for revenge. Easy peasy! Since nothing and no one can escape Tiamat... Or at least, that's what she believed before meeting the one who will push her to make the ultimate choice ans discover all the secrets and lies that have drivent her to become who she is. Will she be strong enough to overthrow the established order and emerge unscathed.
