'The One and Only Ivan' is also a great option. It's based on a true story but is told in a fictional way. It has elements of friendship, hope, and the real - world struggle of animals in captivity, much like some works in the vein of 'hello universe'.
In a fantasy fiction book, 'hello universe' might be used to show the characters' sense of wonder. They are greeting the universe, which could mean they are in awe of the magical and mysterious elements of the world they live in. It might also signify the start of a discovery, like they are about to learn about the secrets of the universe within the story.
