Miss Peregrine's~ Zack Keehbauch

The book I chose to read was Miss Peregrine's Home for Peculiar Children. I chose this one out of all of the other ones because it seemed more interesting, and it is a horror book, that grabbed my attention. So far in the book, Jacob is the main character; he's telling the story. When he was a boy, his Grandpa Portman told him stories about when he was a boy. The stories were real, and Jacob believed him and told them at school and was made fun of since. He then is 16 working at his family's business, Smart Aid, and he gets a call from his grandpa freaking out saying "They're coming for me!" and just going crazy. Jacob didnt think anythign of it because hes done stuff like this before. Jacob calls his dad and his dad asks Jacob to go over there. Jacob calls his friend Ricky to come pick him up and he does. They go over to Jacob's grandpa's house and he's not there. My question is where is he at? What happened to him? Are they gonna find him?
