OOM –
I don’t object to people liking those books, but if insist on naming them the BEST series then I will be forced to beat them over the head with my hardcover single-volume The Lord of the Rings. and drop the collected Discworld works on their toes.
And I shall then inform them that there is such a thing as The Silmarillion and the Unfinished Tales before asking them to play spot the difference between Twilight and True Blood.
