反撃の海峡 (ハヤカワ文庫NV)

The detailed backdrop adds so much depth to the story. I wonder what research or real events influenced Higgins's choice of time and place.

Some characters seemed to operate in shades of gray, making it hard to tell who the real villains and heroes are. What did others think about their moral ambiguity?

Balancing action with character development is tricky, and Higgins managed both well. I'm curious what led to that storytelling approach.
