Bertha, a very young bat, frightens her family once too often and is sent outside to play. She swoops down merrily on a strangely costumed crowd of little humans and yells, Boo! To her surprise, the little humans are not scared! It's Halloween night and everybody thinks Bertha is just trying to get in on the fun. How can a little batty bat scare anybody when they are all dressed up for trick-or-treat? This charming story is perfect for spooky lights-out reading and contains special glow-in-the-dark pictures for added surprises!
