Over at Delaware Online you can find host of new Halloween titles, including Lisa Desimini's Trick-orTreat, Smell My Feet and the Halloween Howls poetry anthology.
Some older favorites around here are The Runaway Pumpkin, by Kevin Lewis; It's Pumpkin Time, by Zoe Hall; The Teeny Tiny Ghost, by Kay Winters; and Too Many Pumpkins, by Linda White. Oh, and I can't leave out Space Witch, by Don Freeman (Corduroy).
If my son were at home, he'd have you reading (for the umpteenth time) The Real-Skin Rubber Monster Mask, written by Miriam Cohen and illustrated by Lillian Hoban. School Library Journal agrees with his assessment, saying "Children eagerly anticipating the next installment about Cohen and Hoban's familiar classroom will not be disappointed by this Halloween treat."
