Andy vs. the Colonel

Burdened by failing to meet her ambitious father's standards, Andrea "Andy" Hollis spites him by enlisting in the army. Her excellent record soon earns her admission to officer candidate school. But when she becomes Executive Officer, she misses being out in the field actively involved in the mission. Her new superior is very casual, easy going, and extremely attractive. Andy is horrified when she develops a huge crush on him.
Newly stateside after a tour in Korea, Cory Costain hopes his new Executive Officer will help him fit in, but is confused when Capt. Hollis is very cold and seems to want no part of a good working relationship with him. What is wrong here? Then a war breaks out in Central America, and the 24th Signal goes to support a multinational effort to regain control of the small nation. While Cory has accepted women in combat roles, he's never had to deal with one as a close subordinate before.
He feels they should at least be friends, just as if she were a man. Is he ever going to find out what has steeled her heart and emotions?
