The PlanetDeath Chronicles

This is an anthology of four individual but connected stories dealing with a controversial topic. They cover a period of time when human induced climate change is an undeniable reality. A reality to be faced here and now. A child that likes to learn, who's playful yet serious makes a discovery. She's an only child who fancies she's a musician, and hangs out with her best friend, Janus. Janus is killer whale and he wants to talk to this little girl.
He desperately wants to talk to her and finds a way to do so. What he had to say wasn't pleasant listening, though.
