The Tale of the Captured Souls

Danielle and her parents rent a lakeside room for the summer where they befriend the young property owner Peter. Strangely the residence is full of mirrors which the owner cites as a "hobby", and even stranger the parents start feeling weaker by the day and Danielle is prematurely hitting puberty. Is this a classic case of growing pains or are Peter and his mirrors the cause of it? (wikipedia.org)
