Dragonsphere

The soul of a powerful dragon has escaped its magical prison.
The creature's wrath knows no bounds and spreads across two enemy kingdoms, forcing an unlikely alliance.
Calderon and Velkyn, the two young men charged with the safeguard of the sphere that held the dragon captive, must leave everything they've known in a quest to recapture the beast before it takes physical form.
Will they be able to stop events beyond their power, or will both kingdoms be destroyed by the dragon's rage?
