The kids spent the night in a fort constructed by the Monsters of the Glades. Well, most of them did, at least. It seems that Talia, Daniel, and Max disappeared during the middle of the night.
When the kids awake the next morning, they find that the Glades Monsters have departed, and also that the sky has grown darker. They need to get the Glades Monsters out of here before they try anything.
Black water seems to be getting closer to them. However, the kids know that they can seal the door to the Glades for a century. Maybe they can seal it away? But can they escape in time?
Whatever the kids are going to do, they need to do it quickly.
