The First 7

Clover Martinez is one of the last teenagers left alive on Earth, and she and her companions have spent their time roaming the stars since abandoning their home planet. Though they have made a life among the galaxy, they still ache for the world they lost. When their ship picks up a distress call from Earth, they cling to the possibility that others made it through. Their hopes collapse on arrival: crystal growths are spreading across the planet's soil and endangering all life on it.

Searching for the source of the crystals, the group finds a community of survivors concealed in the mountains. Their welcome quickly turns to alarm as the teens begin to suspect the newcomers are not what they claim to be. Clover and her friends now face the possibility that they may not get away.
