Upvoting on books mentioned by others but which didn't make my list.
A Fire Upon The Deep - wonderfully epic SF
Farewell My Lovely - anything and everything by Chandler, really
Red Harvest - and by Hammett
Heart of Darkness - let's add Conrad to the list of anything and everything they wrote
I don't have a favorite, and can neither name fiftneen, but I did like:
How To Train Your Dragon
( very childish humor at times, for obvious reasons, yet overall an okay read. Can't say I enjoyed the "viking" names though. Truly, the dragons were named better ),
Guardians of Ga'Hoole,
Don't you Dare Read This, Mrs. Dunphrey,
Wolves of the Beyond,
The Tale of Despereaux,
and Wings of Fire.
To Where the Wind Goes (Haim Be'er, Hebrew, not translated, as far as I know)
Journey to the West (4 volumes, Yu's translation)
Of Mice and Men (a novella, really)
Small Gods, Terry Pratchett
Thief of Time, Terry Pratchett
Joseph Conrad, not sure which to choose. Did you know that English was not his native language?
I like many others, but the above stick in my mind.
