What Book?

Time to treat myself to another book to go on my Kindle. Problem is choosing one!

Any book that catches my eye I add to my Goodreads.com account so I have a continually growing list of books to choose from. What I choose depends a lot on how I feel so at the moment I have a list of three books. So which one do I choose?

Viral Jesus: Recovering the Contagious Power of the Gospel by Ross Rohde

Jesus: A Theography by Frank Viola, Leonard Sweet

Any suggestions most welcome!
