The Cup of Life — Carol Hightshoe

The Holy Grail - The Cup of Christ - The Cup of Life - said to grant one who drinks from it immortality.

A Roman soldier steals the Cup of Life from a small church in Britannia - seeking to carry the Cup to Rome as a prize, but finds himself tempted by the legend that those who drink from the cup will have eternal life.

What the legends don't talk about is the price of that eternal life.
