The covenant that was meant to keep the wizard wars at bay has been stolen, and Trinity must prepare for attack. Everyone is doing their part - Seph is monitoring the Weirwalls; Jack and Ellen are training their ghostly army; even Anaweir Will and Fitch are setting booby traps around the town's perimeter. But to Jason Haley, it seems like everyone wants to keep him out of the action. He may not be the most powerful wizard in Trinity, but he's prepared to fight for his friends. When Jason finds a powerful talisman - a huge opal called the Dragonheart - buried in a cave, his role takes on new importance. The stone seems to sing to Jason's very soul - showing him that he is meant for more than anyone guessed. Trinity's guardians take the stone away after they realize that it may be a weapon powerful enough to save them all. Without any significant power of his own, and now without the stone, what can Jason possibly do to help the people he cares about - and to prove his mettle?
