I'm not sure if 'Death Wish a major new novel' is a best - seller. There's not enough information provided just from the title to determine its commercial success.
It's not a true story. 'Death Wish' is purely a fictional creation that might draw inspiration from various elements but is not rooted in real events. The plot and characters are made up to engage the audience.
Well, 'death wish novels' often deal with themes related to characters having a strong, often self - destructive desire. They might explore the psychological aspects of such a wish, like characters who are in extreme situations, perhaps suffering from depression or a sense of hopelessness, and their journey through that dark state of mind. It could also involve stories where characters court danger or take actions that seem to go against the basic instinct of self - preservation.
Well, without more context, it's hard to say precisely. But generally, an 'original death wish story' could be about a person's extreme desire for self - destruction. It could be related to a revenge plot where the character feels that dying in the process of getting revenge is a worthy end. Or it could be a story of a person in a post - apocalyptic world who has lost everything and simply wants an end to their suffering.
The Death Wish movie has some roots in true events, but it also adds fictional elements for dramatic effect. So, it's a blend of reality and creativity.
