Grey or ashy tones and so on, hena tatoo kit, book of cool fake tatoos with dragons or punk rock stuff, a Guinness world records book or rippleys believe it or not as everyone likes cool and funny stuff, some cool black, green, or dark purple jelly earphones, jewelrey with spikes or skulls and anything else you can think of. Maybe some temporary hair dye or chalk? Just whatever she would think is cool.
What does she wear, has she ever said "oh that looks cool"? What music does she like? What movies does she watch or books does she read?
Look at her writings or drawings/art or posters if she has any. Does she like cars or hunting? Vampires, wizzards and fantasy or anime junk?
Is she athletic? A gamer? Try to do some undercover snooping to see what she likes.
What do her friends like? Perhaps you could ask them or see if they have similar intrests or styles? Best of luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
