Day of War is a powerfully, realistic dramatization of how life might have been for King David, Israel's second King, and his mighty men. It is very closely based on Old Testament Scripture during the time in which David had already been anointed King by the prophet Samuel, yet not on the throne, since King Saul was still reigning. This is an extremely violent time and is portrayed as such, but who better to write about such things as the author of this book, who serves in the military and has himself been acquainted with the possibilities of terrifying battles. The underlying theme of "the covering" throughout the book was especially appealing to me. You need to read it to discover this "covering" in the time of war.
