The books certainly ignored the darker aspects of the war. A cute little blonde like Luna would have been ridden long and hard during captivity. She would have most likely been emotionally broken. The same was probably happening at Hogwarts to both genders.
A giant wicker man on Hogwarts lawn burning a nice chunk of the purists would be a sight to see.
I love stories where Harry winds up with Luna. She is far and away the best pairing, for canon Harry with Hermione as a distant second. The fangirl was the worst.
