Karra doesn't remember why she was sentenced as an Eligius 4 miner . . . or why her best friend Zeke Shaw is with her. All she knows is that the world she came from is gone and survival is the only thing that matters. Bellamy has Clarke back in his life again, but at what cost? His sister has become the leader of a fanatical cult of gladiators, and the Ice warrior he loves is slipping away. Life on the ground has never been easy, but this time the stakes are higher. Clarke loves Bellamy, but six years is a long time to wait for someone. And the protection of her home is more important than the happiness of her heart. She's lost enough already--she isn't going to lose the valley that saved her and Madi. After six years of peace, war has returned. Once again, strangers threaten the lives and safety of Clarke, her people, and Wonkru. But this time they are not children new to fighting--they are survivors. They are grounders. And they are going to fight for their home. [yet another s5 speculative/AU book from me featuring another Eligius OC!! will probably become a speculative s6 series, too]
