Horizon - Scott Westerfeld

This harrowing tale of supernatural suspense kicks off a new series
from the visionary mind of #1 New York Times bestselling author
Scott Westerfeld.
When a plane crash-lands in the arctic, eight young survivors step
from the wreckage expecting to see nothing but ice and snow. Instead
they find themselves lost in a strange jungle with no way to
get home and little hope of rescue.
Food is running out. Water is scarce. And the jungle is full of threats
unlike anything the survivors have ever seen before--from
razor-beaked shredder birds to carnivorous vines and much, much worse.
With danger at every turn, these eight kids must learn to work together
to survive. But cliques and rivalries threaten to tear them
apart. And not everyone will make it out of the jungle alive.
