A mysterious and frightening shadow has been skulking its way through all the realms of myth and legend. Its sinister presence is always followed by an attack of such evil violence that few survive. Jacob - Battle for Olympus - is the last in a riveting five book series. It concludes the story of Jacob's journey to be the God of Gods and his battles against the Dark side. In this instalment he finally establishes who Shadow is and quickly learns it can only be defeated with the assistance of the Ancient One. Jacob's heart breaks on learning of attacks by Shadow on the Dragon, Elf and Yeti nations and is devastated when he discovers many of his friends and allies have been killed. When Asgard is destroyed he concludes that Shadow's plan, just like that of The Darkness, is to destroy all that has been created by the Ancient One. This emboldens him to awaken the defenders of Olympus who have, since long before the time of Zeus, been sleeping deep in the caverns below the temple. Can Jacob rescue the remnants of those of myth and legend? Will the Ancient One come to Jacob's assistance? Is the Battle for Olympus to be the battle to end all wars?
