Luisa Wenz, the truth in the shadows

Luisa's life couldn't get any more stressful than it already is. First her parents split up, then she has problems of her own, and then, when she finally has the chance to go on holiday with a youth trip to Vienna, she discovers that there are people who are reincarnated historical figures. Not only that, but she is one too. But she has to find out whose historical figure she is only after her trip back home, at a place where the other reincarnated people spend their holidays, but that won't happen. Because the people in high ranks are hiding something, something that everyone deserves to know, because it threatens their lives, but which could also trigger a series of adventures that ask what she will have to sacrifice or lose.
