YA Fantasy published around 2005 to 2010

[Preksha]

The Genre of the book is YA Fantasy, 2 or 3 kids children maybe? It was set in an East Asian country where the world was ending, the girl has a jade necklace and that was important. The cover of the book was green it was the second book in the series, I do not remember the author's name. The plot of the book was linked to a prophecy
