The Robe by Lloyd C. Douglas

It is a 'Fiction/Religion' book ,just so you all know before hand.

It was recommended to me by a friend, and I thought it was really good.

The Back of the Book wrote:

A Roman soldier, Marcellus, wins Christ's robe as a gambling prize. He then sets forth on a quest to find the truth about the Nazarene's robe - a quest that reaches to the very roots and heart of Christianity and is set against the vividly limned background of ancient Rome. Here is a timeless story of adventure, faith, and romance, a tale of spiritual longing and ultimate redemption.

Even if you are not Christian or religious, I still recommend this book.
To warn you if you do read it, the beginning is slow but it picks up after the first chapter.
