Nico, Opal, Emma, Tyler and Logan are back. The DarkDeep keeps spitting out figments even though no one is going through it anymore. They don't know where they are coming from, but they are able to dispel them. It is getting close to Halloween, the "Beast" has become popular and is bringing in tourists, and now a You-tuber shows up from Freakshow to document what he can find. As the kids try to figure out what is going on with the DarkDeep, the green blob starts to communicate with them, the figments start becoming where they can't be dispersed, and the you-tuber starts discovering more about what's going on. Will the kids be able to contain the chaos?
Another great addition and a window left open for another book! Can't wait!
