The YA contenders are:
A Corner of White, by Jaclyn Moriarty
Voyage of the Unquiet Ice, by Andrew McGahan
The Convent, by Maureen McCarthy
Friday Brown, by Vicki Wakefield
Wildlife, by Fiona Wood
Interesting that the artwork seems to skew older than in the States; judging by covers alone, I'd have guessed that at least three of the five were adult titles.
