The Sting of the Bee (Melt Trilogy)

Catastrophic global warming has melted the ice caps and John Barrous will stop at nothing to stake his claim on the rich, virgin continent of Antarctica.
 
After the murder of his wife, John escapes urban strife for the quiet life of farming. He and his fifteen-year-old daughter join in a United Nations PR event, but the Oklahoma-style land rush turns into a race against ruthless, armed competitors . . . and a corrupt politician determined to control this new land.
