I don't know who the main characters are since I haven't read the novel. But generally, in a novel with such a strong title, the main characters are likely to be those in a relationship where one has these extreme feelings towards the other.
Perhaps the main theme is about the dark side of human emotions. In the novel 'There were times I wished you were dead', it may show that even in normal - looking relationships, there can be hidden depths of animosity. It could be exploring how these negative feelings can fester over time and what it means for the individuals involved. It might also be a commentary on how difficult it can be to overcome such extreme emotions and how they can shape a person's view of another.
I'm not sure specifically as I haven't read the novel. But usually in a novel with such a title, there would be a character who harbors the 'wished you were dead' feeling towards another character. So there would be at least two main characters in this kind of conflict - ridden plot.
The main theme could be about complex relationships. It might explore themes like hatred, revenge or the extreme emotions that lead a character to wish someone dead.
It's a really intense and thrilling story. The plot involves a world where the dead have a chance to play a mysterious game for a second life. The appeal lies in its unique concept and exciting twists.
I'm not overly familiar with this specific book, but generally, an adoption story book can be really heartwarming. It may detail the journey of how a family was formed through adoption, including the process of longing for a child and finally having that wish fulfilled. 'I Wished for You' might have some unique elements in its narrative that set it apart from other adoption stories.
