For Zilzal, I'm guessing it would probably have have been National Velvet by Enid Bagnold.. or Black Beauty by Anna Sewell
I like fiction so I just read the Tony Stewart interviews.
Animal Farm is pretty easy to re-read as it's short.
Have re-read Lord of the Rings a few times but that's about it, there are millions of books I haven't read so why re-read the ones I already have read?
