Young Warriors (Wine of the Gods Book 10)

It's traditional for young lords in the Kingdom of Ash to spend two years in the army. Xen Wolfson is a young wizard, and Garit Negue a young prince. And the world is filled with adventures and danger . . . and learning experiences.

Their world has been in sporadic contact with two different cross-dimensional worlds--generally as a target for conquest. When the Empire of the One returns, the young warriors are standing foursquare in their path.
