by Paul L. Maier
This was historical fiction based on the life of Pontius Pilate. Although I've read about the trial of Jesus Christ many times, this story, based on a Roman perspective, was refreshing and unique.
It helped me understand Pilate's strong political motivation to crucify Christ even though he knew Him to be innocent. While not excusing Pilate, because ultimately, he did what he wanted to do, it showed that when faced with the choice of doing what was right or saving his political skin, he chose self-preservation.
It gives great background into many other historical figures and events of the time. I highly recommend this book.
