Just when we thought we'd seen it all, the supernatural quotient gets turned up to eleven in the final chapter (which just so happens to be… Chapter 11), making us crave more for the sequel.

By the end of the book, after Jacob has rescued Miss Peregrine, he gets the kind of admiration from the other kids that his grandfather should have received in life.

This is perhaps the most important thing Emma can say in her letter to Jacob's dad. Maybe it will let Dad finally see what a good man his own father was, and give him what he needs to become a good man himself.
