Prologue + Main Cast

I, Rayleigh Griffin, daughter of Jake and Abigail Griffin and older twin sister of Clarke, was born in space. I've never felt the sun on my face, breathed real air, or floated in the water. None of us have. For three generations, the Ark has kept what's left of the human race alive. Only now our home is dying, and we that remain are the last hope of mankind. A hundred prisoners, me and my sister included, are sent on a desperate mission to the ground. Each of us is here because we broke the law. However, on the ground, there is no law. All we have to do is survive; but we will be tested by the Earth, by the secrets it hides, and most of all by each other. This is that very tale, of the trials we will face, given to us by Earth herself.
