Magic to Be Proven

In the second week of sixth grade, Hermione Granger stopped a boy from the same school in the common room. His name is Li Tianyu, he is a Muggle-born, taciturn, with good grades but never attracts attention. He was writing a paper - one that claimed to explain the nature of magic using Muggle physics. Hermione thought it was just an ordinary academic curiosity. What she doesn't know is that this paper will involve her in a much bigger game than she imagined: Professor Flitwick's late-night meeting, Slughorn's candied pineapple, a secret laboratory with three protective spells - and a secret that has been kept for three years, and finally found someone to entrust. But truth is never cheap. In an era when Voldemort was getting closer and closer, the phrase "magic can be understood" was not an academic statement to some people's ears, but a statement of defiance. And when the shadow of war spreads within the walls of Hogwarts, they must face a more cruel problem: Are some truths worth trading everything for?
