This book has become a book of my heart, too. I've read it 3 times now, and I love all your books (I put the Feed trilogy into the hands of any patron I can). My copy of Every Heart a Doorway showed up in my mailbox the day after I was gifted with a small silver charm of a door with a heart shaped key dangling off it. I shall actually vote in the Hugos this year (most years I do if I remember).
