The main theme of a Pacific High novel can vary. It might center around friendship, coming of age, or even a mystery to be solved. It all depends on how the author crafts the story and the elements they choose to focus on.
I don't know as I haven't read it. But usually in a novel about love, there could be a male and a female lead.
Since I don't have the book in front of me, it's hard to say precisely. However, 'tainted love' might imply a love that is somehow corrupted or not pure. And the 'Pacific High' in the title could be a specific location like a high area near the Pacific Ocean. The novel might revolve around the story of lovers whose relationship is affected by various factors in that Pacific - related setting.
The main theme could be about the struggle between the powerful and the ordinary. It might show how those in high positions interact with others and the impact of their actions on different characters.
One main true story is about the Battle of Guadalcanal. It shows the Marines' struggle in that tough battle. Another is about the experiences of individual soldiers, like their relationships and how they coped with the stress of war.
One of the main features was its large size. It was extremely heavy and had a long boiler. Also, it had four cylinders which was quite unique and contributed to its great power.
Most likely, the main theme is love. Given the title, it's probably about a romantic relationship in the High Sierra.
In the Pacific Rim original story, Raleigh Becket is a main character. He's a Jaeger pilot who has his own backstory and experiences. Mako Mori is another important character. She also becomes a Jaeger pilot. Stacker Pentecost is a key figure as well, leading the Jaeger program.
One of the main true stories is about the Battle of Guadalcanal. It shows the Marines' fight against the Japanese forces in that crucial battle. Another is the experiences of the soldiers dealing with the difficult terrain and climate in the Pacific islands.
Facts in 'the pacific' are things that can be proven. For instance, the types of weapons used during the Pacific War. Fiction, on the other hand, is more about creative storytelling. It could be things like the thoughts and feelings of characters that are not based on real accounts but are created to make the story more engaging. Maybe a character's superstitious belief that affects his actions in the story is fictional.
I'm not entirely sure, but it might include the Jaeger pilots. They are the ones at the heart of the action, fighting the Kaiju. Maybe Stacker Pentecost or Raleigh Becket could be among them if their stories are continued in the graphic novel.
