The Dragon Engine — Andy Remic

Five noble war heroes of Vagandrak get drunk one night and sign a contract -- to journey to the Karamakkos in search of the Five Havens where, it is written, there is untold, abandoned wealth and, more importantly, the three Dragon Heads -- jewels claimed to give unspeakable power and everlasting life to those who wield them.

But the Dragon Heads aren't what they think, and the world has not encountered their like in generations!

Think Smaug was fierce? You ain't seen nothing!
