This book is undergoing a major revision and will be completely rewritten.
Two good brothers were reborn, but the universe was plunged into tragedy. They are two independent consciousnesses in the form of celestial bodies: a supermassive black hole and a supermassive white hole.
The universe is actually a gathering place for delicious treats. Frozen liquid planets are ice cream, supernovas are mints, red supergiants are spicy beef meatballs, ordinary black holes are popping candy, and quasars are platters of delicious barbecue.
Then the universe's super alien civilizations must be banquets fit for an imperial feast.
