For two seasons, 'The 100' refugees sent to Earth have been at war: with themselves, with the Grounders and with Mount Weather. Many have lost their lives. All have lost their innocence. They've learned that in the fight for survival, there are only the living and the dead. Now the survivors have returned home to a world seemingly at peace. But can they find peace within themselves after what they had to do to escape? And is there more to life than mere survival? Their newfound sense of normalcy will be short-lived and their lives changed forever. Prepare for the 16 grittiest adventures ever as threats old and new test the survivors' loyalties, challenge their limits and make them question what it truly means to be human.
