"Momo" and "Neverending Story " by Michael Ende.
"The Time Machine" by H.G. Wells.
"Faust" by Johann Wolfgang von Goethe (technically an opera, not a book).
"The Divine Comedy" by Dante Alighieri.
The "Odd Thomas" series by Dead Koontz.
"Sygdommen til Døden" by Søren Kierkegaard.
That about sums up what I have actually read and enjoyed within the last decade.
