Changing the glade

Gemma is the new girl in the glade. she comes to the glade in the box just like everyone else.
But Gemma's different.
She's the only girl.
To make things stranger the creators controlled Gemma's body bringing the gladers a message and leaving her in a coma.
The gladers are suspicious when events turn to the unnatural. Gemma is to blame for these events and who knows what's lurking in these wild people's brains, and what they could do to Gemma.
