It is the first book of a trilogy, Orn and OX being the second and third book of this series. Omnivore is the story uncovered by a futuristic superhuman government investigator named Subble while investigating the disappearance and murder of eighteen space explorers on the exotic planet of Nacre. As the investigator's mind is wiped completely clean after each mission to eliminate any bias, Subble must uncover the clues to this mystery through interviews with three suspects (Veg, Aquilon, and Cal) as well as a few more unconventional tactics.
Through quite short, Omnivore is a thorough and intelligent science fiction story. The parallels between the inhabitants of the planet of Nacre, the three suspects, and humankind in general is extremely intriguing and timeless. The concepts behind the workings of the planet of Nacre itself are very creative and clever. The characters are creatively realistic with a touch of 1960's nostalgic spirit. This unique mixture creates a story that is both entertaining and thought provoking.
