Seibold, J. Otto and Siobhan Vivian Vunce Upon a Time. Chronicle Books, 2008. PICTURE BOOKS. A young vampire is extremely fun of candy, but one day his stash runs out. A passing skeleton clues him in to the upcoming Halloween night. Dagmar enjoys his evening out with the ghost he met on the street, until the ghost takes off her costume, revealing a human underneath. Scared, Dagmar runs off and then the human proves herself to be a good friend. This is a lovely little Halloween book. I love the funky illustrations from the man whose work you might remember from Olive, The Other Reindeer. And Dagmar is an endearing vampire. EL - ESSENTIAL. Cindy, Library-Teacher.
