The White Darkness
Geraldine McCaughrean
 Shy teenager Symone ‘Sym’ Wates is taken to Antarctica by her domineering 'uncle', Victor Briggs, who after the death of her real parent has elected himself her surrogate father. An obsessive believer in the hollow earth theories of John Cleves Symmes, Jr., Briggs is convinced that in Antarctica he will find the entrance to the Inner World and its inhabitants. He is ready to sacrifice Sym and others to prove his theory, and increasingly puts her in danger until she finally sees the truth about him. She is then able to escape his plans for her. Briggs dies still pursuing his obsession while Sym returns to her own life with a new freedom.
