Query: Celtic Fire

Britania is not the choicest posting for a Roman commander, yet that is where fate leads Lucius Acquila. Not only is he sent there by human order, but also by the ghost of his murdered brother. Somewhere among the wild pagans, the answers he seeks surely lie. The lynchpin to his quest is the beautiful slave queen Rhiannon, though he does not realize this for some time. They should be enemies, but are drawn together by something greater than blood, revenge, or politics. Fans of Morgan Llewlyn or Parke Godwin will find this very similiar to their writing. Though classed as paranormal, that is largely a misnomer. The murdered brother's spectre is not a dominant factor to the story.
