The Runes of Sorcery (The Runespell Trilogy #3)

The third book in the "Runespell Trilogy". Caspar, Brid and Hal have traced the lost runes in the Yew Forest in the heartland of Farona. Etched on the bottom of a cauldron, the runes tell the location of the Druid's Egg, an object of such fearful power it has long been hidden in distant lands.
