Peculiar Children 2

In this part of the book. The little boy is grown up. Jacob works at a store and he hates it. Well one day when he is at work his grandpa calls him saying basically that he is not safe and that the monsters are coming. Jacob told him that he would come over but his grandpa told him not to because its not safe to. Jacob calls his dad to tell him about what is going on and his dad wants to put the grandpa in an old folks home. Jacob doesn't want that though. My favorite character so far is the grandpa but I feel like something bad is going to happen to him.
