The Centurion's Wife by Davis Bunn and Janette Oke
The only reason I have this book is it was free on the Kindle. But I was intrigued by the story. Then the more I read the less I wanted to put the book down! Would I recommend this book - YES! It is in the genre of Christian fiction.
It takes place in Jerusalem between Christ's crucifixion and Pentecost, or the week after Pentecost. It's the story of a centurion who is told to find out what the disciples did with Jesus's body and the story of a servant to Pilate's wife who is told to find out if the disciples plan a rebellion. Well sort of. And it's really so much more than that as well. :-)
