In a sweet hell where everything is made of candy, immortality is a slow torture. Lawyer Keyes can taste every flavor of lies. This ability comes from a piece of "eternal toffee" from alien remains in his body. When a chocolate door that leads directly to the center of the earth appears out of thin air, he is forced to face the inhuman consciousness that has been imprisoned for five hundred years - the "Silent One". To end the immortal curse, he must understand incomprehensible logic and translate unspeakable languages. However, he discovered that those black monsters born from lies were actually the lonely cry for help from the gods. Healing oneself means extinguishing the only fire of communication between the two worlds. The tip of Keyes' tongue will decide whether this bitter misunderstanding across the galaxy ends in sweet destruction or reconciliation in eternal silence.
