However, their long-standing enemy, Dr. Khalid, is following them as their travels take them from Oxford, England, to Scotland, where the location of the quest is in an old castle, a ruined chapel, and with a few ghosts thrown in as well. Little do they know there is another deadly force, the Eaters of Poison, who have their own mission to complete. Who are these enigmatic and scary Eaters of Poison, driven by an ancient purpose? What is their connection to the castle's past and James’ ancestor, Bedwyr the Curious Monk, whose research into history started all the trouble? Time is running out as the confluence of the planets draws closer. Can Justin and Adam find the second Stone of Power and survive? And why did Aunt Isabel send a girl with them?
Join Justin and Adam as they search not only for the second Stone of Power, but also for the Scroll of the Ancients, a mysterious document that holds important clues to the Seven Stones of Power. Right from the start, this adventure is not like the first. As their new adventure unfolds, they learn many things and face dangers that make even their perils in Egypt look tame. And how annoying for them that their tag-along companion, Kim, seems to have such good ideas when they are stumped.
