This month has only been marginally better than September as I managed to finish three books this month:
Possession - A. S. Byatt
The Cross of Christ - John Stott
A Book of Narrative Verse - compiled by V. H. Collins
Neither A Book of Narrative Verse or Possession did much to change my life, however The Cross of Christ did. Thus is makes to book of the month for October '14. You can find out why I liked it so much here, but the best thing that you can do is to read it for yourself.
What I will say about it is that, although the book is a doorstop, it is rammed full of good stuff that it is well worth working through. The good thing about this book is that it is so well written that you can forget that you are reading a book that is full of serious material. But it does mean that thinking about how Christ's life and death affects you is unavoidable.
