Rebecca Grabill has been a zombie, a witch, a ghost, a vampire, and a whole lot of other less-ghoulish creatures--for Halloween. When it's not Halloween, Rebecca is herself: a writer and mamma of five humans. She and her husband and humans live in Michigan along with numerous chickens and two cats. Visit her at RebeccaGrabill.com. Ella Okstad loves to draw ghosts, vampires, humans, cats, and all sorts of creatures. She lives and works as an illustrator in Trondheim, Norway. When she's not in her office creating scary, cute, or peculiar creatures for books, she enjoys spending time with her husband, three boys, and a cat. Visit her at Okstad.com.
