I believe this book is going to be the first in a series, and I gave it a rating of four out of five. Jacob's grandfather tells him many strange stories about people he knew as a child. He even has photographs, but they are too peculiar to actually be true. I mean, a girl with fire in her hands, another who can make herself rise off the ground, a boy who is invisible, and another child with a mouth in the back of their head? It all seems too wild until Jacob's grandfather is attacked and killed one night. Jacob starts having bad dreams, and it's decided that visiting the home in Wales where his grandfather grew up will help. Jacob can't believe what he finds there, and he may be the key to saving many lives, possibly the world.
You need to be prepared to think if you choose to take on this book. Obviously, grandfather's stories turn out to be true, and the book is full of photographs of the various characters. In addition, the plot involves a time loop and additional creatures that will require you to use your imagination. Jacob finds himself traveling between today and 1940, and he knows he will eventually need to choose to stay in one of the settings. The exposition of the story describes some evil characters who remain free and Miss Peregrine may be stuck in a morphed body. The children set off to make things right. Sequel!
