Mirror People/ Contest Short Story

Synopsis from Mirror People:
When Lucie Dare was eight years old, she was taken away from her uncle's care on reports that he had gone mad. Before she left, she could recall him throwing his life's work, his research, into the fire and shouting to the maid, "The world isn't ready."

Her uncle once said to her, placing his hand on the cold glass of the mirror. His reflection doing the same. "What if-" he whispered. Eyes fixed on his own eyes, across the glass. "We can't get through the mirror, because our reflection is stopping us."

And shortly after he went mad, "What if our reflection could get through the mirror, too, but we are the ones stopping it."

Now Lucie is going to find out what exactly was her uncle referring to.
