It could be about the redefinition of beauty in relation to life and death. 'Life eternal' might represent an idealized state, while 'a dead' brings in the reality of mortality. The 'beautiful' in the title might indicate that the novel explores how beauty can be found not only in life but also in death and how the two are connected in the context of an eternal life concept. It could also touch on themes of acceptance of death as part of an eternal existence, and how that acceptance can lead to a new perception of beauty.
