Gung-Ho: Anger (Gung-Ho: Anger #1)

Archer has been banished from the colony, falsely condemned for the rape of Celine. But Zack doesn't believe in his brother's guilt, so an expedition is launched into the danger zone. Unbeknownst to the rest of the community, the teens go to look for Archer... if he is still alive. The expedition will not be without risks though, nor without unpleasant surprises...

Back at Fort Apache, confusion reigns and tensions are at an all-time high, as the adults look to safeguard the young and keep the colony intact. But with a "white wave" approaching, is it already too late?
