Blood of mystery - Mark Anthony

In this final instalment of the epic LAST RUNE series, Grace Beckett and Travis Wilder face yet more challenges on Eldh, the realm of gods and monsters, myth and runecraft, whilst in Denver, preacher Sage Carson is being ordered by the Big Voice - an unknown evil - to cull his flock. He must create more ironhearts to fight on the Day of Judgment...
Earth and Eldh are drawing ever closer. Grace and Travis are in pursuit of the knight Durge, for if he reaches Mordenfale with the two runes, the Pale King would be able to open the gate to Eldh for Mohg, his master. When they reach Durge, he begs to be slain, for he has turned into that which he always fought against. Travis contests this, threatening to break the Rune of Death.
Yet Travis's greatest challenge lies in discovering where the First Rune is hidden and how to bind it so it can never be broken.
