Ice Cold (Sequel to Tidepool)

8 year old Raiz Grace wakes up in the middle of a camp. A camp of Raiders, a people who attack his home every year. The last thing he remembers is water. Raiz has a chance to survive though. If he proves he is stronger than the children of these barbarians; he can live. If he fails, he will die.
Along with trying to get home, he must pass tests that will either make or break him.
Is Raiz strong enough to live among these people?
