There are three things about this WIP that really challenge me:

1) It’s a new genre for me. Each genre has their easy elements and their hard elements, but when you switch genres there’s a learning curve.  

2) I’ve never worked with a cast this big. Keeping track of who knows what when requires a spreadsheet and notes.

3) Being an amateur modern military historian means I’m extra sensitive to battle strategies, the realities of war, and how quickly things go wrong. This makes me constantly doubt my war scenes and fret over upcoming battles.
