Ransom Riggs said this quote

When I was a kid, Granpa Portman's fantastic stories meant it was possible to live a magical life. Even after I stopped believing them, there was still something magical about my grandfather. To have endured all the horrors he did, to have seen the worst of humanity and to have your life made unrecognised by it, to come out of all that the honorable and good and brave person I knew him to be - THAT was magical.
