I don't know since I haven't read it. It could be a young couple perhaps.
I don't have information about this novel so I can't tell who the main characters are.
Another possible main character could be an older person. They may have lost their life - long partner. This character would bring a different perspective to the story, perhaps having a wealth of memories and a long - established way of life that is now completely disrupted. Their journey through this new 'life without you' situation could be very complex and full of different emotions.
Without having read the 'lost without you novel', it's difficult to name the main characters precisely. But we can assume there is a main character who is at the heart of the story's emotional turmoil. There may be a secondary character who has a significant impact on the main character's life, and whose absence causes the main character to be lost. There might also be characters in the background, like neighbors or colleagues, who play a role in the main character's journey of self - discovery in the absence of the important person.
The main character is likely a strong - willed individual. Maybe a former military or someone with a special set of skills.
I don't know as I haven't read the novel. Maybe there's a protagonist who is left behind when someone else leaves without a word, and the person who leaves could also be a main character.
Since I haven't read the novel, I can't say for sure. But it could be a couple, like a man and a woman where one of them is absent for seven days.
The main character is the man without a face. There could be a female character who is intrigued by him. She might be a curious soul who wants to understand the mystery behind his lack of a face. There could also be an antagonist, perhaps someone who wants to use his unique condition for their own malicious purposes, like in a scientific experiment or something.
I'm not sure as I haven't read the novel yet. But they could be survivors in a water - less world, like a scientist trying to find a way to get water, a mother trying to protect her children, or a group of adventurers on a quest for water.
Since I don't know the details of this novel, it's hard to say exactly. However, in most novels about love, there are likely to be the two people who fall in love, perhaps with some supporting characters around them like friends or family members who influence their relationship in some way.
Maybe there's a protagonist who is on a journey to discover more about these nameless birds. This character could be a scientist trying to study them, or a lost soul who finds solace in observing these unique birds. And then there might be secondary characters who either help or hinder this main character's exploration.
