The heart of the night. Korsakova T.

Like the very focus of darkness, there is a gloomy tower among the deaf taiga. None of those who tried to find her returned back. Only a conductor with a key is able to cross the border and lead his companions to the goal, but are they all the same to meet the faithful death?

Three girls - a daring Elsa, a capricious face and timid Martha - are not at all like each other. But fate was not in vain brought them together, because each of them has special abilities and each has to go through their test and find the way through darkness.
