Skeeter and Pandora

Skeeter Bridges, 15, and Pandora Roberts, 15, are the only two humans awake in their world when the stars all die.
They're also the only two humans left alive.

The two teens witness what happens next, and must defeat their enemy, within only a month.
But they're only a mundane farm boy and an exceptionally flexible girl against a whole army of intruders.

Until they find that with the dying of the stars came new found powers.
