Letitia Uncrowned

Letitia and Godfrey Gorm are retired monarchs living lives of Caribbean tranquility in Tobago, but when Melloria, their former kingdom, is invaded by Slobodia they fly back to join the fight against the invaders. Capture and incarceration follow, made worse for Letitia by being forced to watch hours of TV soaps and quiz shows in her prison cell.
Her rescue by Live-Action Role Players disguised as dreaded Slobodian prets brings little relief since Godfrey is missing. He has been flown to the lair of Royston Slovo, Slobodia's new megalomaniac leader, and is forced to witness atrocities inflicted by Royston on a female prisoner to make him accept the role of Melloria's puppet king.
He suffers a physical collapse without agreeing to the role and is left to rot in a dungeon.
A daring rescue by the role-playing Sons of Nordik reunites him with his wife and sons in exile in Bulimia.
Along with King Craig and his mother Sharon, also in exile, they watch as the underdog Mellorians slowly but surely win their freedom by strikes which hamstring the Slobodian army and musical and sexual inducements which sap its morale.
Royston's plan to plunder unlimited supplies of oil from within the Mellorian Fissure proves to be the Slobodians' nemesis. First he is the object of a Mellorian 'self-assassination' and then his successor, Queen Latrina, is lost in a gigantic conflagration at the Fissure Well - a catastrophe that leaves Letitia, flying back to Tobago with Godfrey, in life-or-death limbo.
'Letitia Uncrowned' is the second novel in the Letitia trilogy. the first, 'Letitia Unbound' is already available.
