The Dream of Scipio - Iain Pears

This is my second Pears book, and it was as original as the first.  The story is an odd one about three different men in three different eras wrestling with decisions and looks back at a late Roman nobleman's writings in something called The Dream of Scipio, copying the title of a writing by Cicero.  The writing is the common thread between all three.  One thing I particularly liked was the constant back and forth among the three stories, and the way the narrator explained how the site of one event in the fifth century or the fourteenth century became the site of something else in the twentieth, thus physically tying the events together.
Overall a really interesting book - I enjoyed it a lot,
