Bones of Frost

Siva is the only living descendant of the Children of Frost. Her people were wiped out, and now she must live among their murderers. In the prison where she was thrown by the evil priestess Jedwiga, she meets Bogobor, a creature whose own will has been stripped away by a curse that forces him to kill. Together, they set out to find the bones of Frost, a powerful artefact that can prevent Jedwiga from opening the gate to Nothingness itself and destroying the northern principalities, one by one. Will they manage to find the god's remains and prevent the destruction?
