Perhaps there's a local character, like a fisherman or someone who lives near the water. They would have a personal connection to the water and could be an important part of the story, noticing the changes in the water first and being involved in the events that unfold.
I'm not certain. But usually in such novels, there would be a protagonist who is likely to be closely associated with the events related to the water. Maybe a detective or someone with a personal connection to the water - related mystery.
The main theme could be mystery. Since there's'something in the water', it might imply a hidden element or danger lurking there, which often creates a sense of mystery in a story.
I'm not sure specifically as I haven't read the 'deep water novel'. But it could be a lone adventurer who is drawn to the deep water for some personal quest, like to find a lost treasure or to prove something to himself.
I'm not entirely sure without reading it thoroughly, but there could be a local fisherman who is very much in tune with the water and the life around it. He might be one of the main characters.
Without having read 'the water family novel', it's difficult to determine the main characters. However, it's likely that there are characters within the family unit who are central to the story. There could be a character who is trying to protect the family's water source, or a character who is in conflict with the family's traditional water - based ways of life. There might also be characters from outside the family who interact with the family in relation to water, like a water official or a neighboring family with different water practices.
One of the main characters is a young boy. He is curious and kind - hearted, which leads him to find the water horse. The water horse is another key character. It has its own unique characteristics and behaviors. There might also be some supporting characters like the boy's family members who play a role in the story, for example, they might unknowingly create some challenges for the boy in hiding the water horse.
Elisa, she is at the heart of the story. Her muteness makes her an outsider in a way, but it also gives her a different perspective. Then there's Strickland, who is sort of the antagonist. He represents the more cruel and unfeeling side of humanity. And the creature, which is the focus of Elisa's affection and the source of much of the story's conflict and connection.
Typically in a novel like 'Something Borrowed', we have the female lead. She is the one who gets into the complicated situation of having feelings for someone she perhaps shouldn't. Then there's her female friend, who is in a relationship with the man the female lead has feelings for. The male character is also important as he is the object of the female lead's affection and is part of the love triangle that drives the story. There may also be other supporting characters like family members or coworkers who add depth to the story by influencing the main characters' decisions or providing different perspectives on the situations they are in.
Since I'm not familiar with the 'Dark Water Graphic Novel', I can't tell you the main characters. But in most graphic novels, the main characters are often those who drive the story forward, face the central conflicts, and experience character growth throughout the narrative. So in this case, it could be a brave adventurer, a scientist trying to understand the dark water phenomenon, or a group of survivors in a world affected by the dark water.
There could be a character who is an artist. Since water lilies are often a subject of art, an artist character might be interested in painting the black water lilies. This artist could be one of the main characters, and through their eyes, we could see the beauty and mystery of the lilies and the surrounding area. There might also be a local villager who has a deep knowledge of the lore and history related to the water lilies, and their interactions with other characters could drive the story forward.
