I'm currently in the process of writing an epic fantasy series of novels, with a series-spanning theme of atheism and pragmatism. Part of the plot in the books involves it being proven unequivocally that no gods or afterlife exist. The effect on society and the characters is explored, and eventually the sinister source of the religious texts in the fictional world (Torea) becomes known.
I currently self-publish and have two book available and a third imminent. I don't want to use this as crass place to plug my work - I won't discuss the books themselves for that reason. However I'm trying to secure a print deal and am in discussion with a literary agent. He asked me to produce a book proposal which includes a 'competing books' section. I'm finding this very hard to complete. I don't know any books which are similar, especially that are fairly recently published and by less known authors.
The stories read a bit like character-heavy fantasy adventure stories, with dwarves, elves, dark elves and dragons and of course, atheism (Though it's subtle in the first book.)
Can anyone suggest some competing books? Comparable works which I can put in my competing books section of the proposal?
