The Tales of Draco

In Cassius to Krigsansby, book three of The Tales of Draco, Jacob and Clipper must rally the Militia to finish their quest once and for all if the nightmare on the first earth is to end. General Czar seeks to introduce Vesuvius's cause to the first earth, and is willing to enslave men under sorcery in the name of "freedom."
Only two pieces of the portal back to Jacob and Clipper's beloved home world, Elsov, remain to be found. But will Elsov be the fanciful fairyland they remember, or have their deeds changed it forever? What if the challenges left on the first earth follow them home?
