Under Ground-Left alone in a secret room after their parents were kidnapped, Diamond and Obsidian must take care of their younger siblings. But how?

The Core-The enemy is closer than ever searching for the core, something so powerful it could sustain the energy of half of the US, but if it were to fall into the wrong hands in a society that is overwhelmingly desperate for energy, it could mean the end of freedom and lives. Watch as Diamond battles with the shadows of her recent past. Her struggle within could compromise the safety of those around her. Ransom-Diamond has left because she thinks she'll keep the others safe. What she doesn't realize is that she put them in more danger than they could ever imagine by taking the core with her. When one of the group members is kidnapped and the core is the ransom, how will they ever find Diamond to get the core back in time to save a life?
