The Golden Ass by Apuleius, the Robert Graves translation, Penguin 1950 edition.
I know, I know, it sounds like a w*nk fest. However, it is one of the earliest complete surviving stories from the Latin era. As an adjunct, I studied Latin at school as a young'un so such books as McCullough's 'First man in Rome' are also favourites because I still have a basic understanding of Latin (which is a great help). The Golden Ass is also quite risque and offers great insights into an earlier culture that is far removed from our own ideas of 'civilisation'.
BTW, a basic knowledge of Latin also stands you in good stead when dealing with either the law or medicine. Both professions are rife with pretentious w@nkers.
Recently re-acquired the Complete Works of Paterson and still seeking the Complete Works of Lawson to replace the originals eaten by white-ants while in storage.
Interested in anything, ranging from archaeology to zoology.
I really enjoyed King's 'Gunslinger' series. A break from his usual horror genre. Ben Elton is a modern Tom Sharpe, love his stuff.
Reading - my favourite non-contact sport.
