Starlight Surprise - Chapman, Linda, RN, PhD

When Lauren whispers the magic words, her pony turns into a beautiful snow-white unicorn. Lauren doesn't believe in ghosts, but there is definitely something spooky going on down by the creek. Then one night, as Lauren and Twilight fly over the woods near the scary tree house, they make a surprising discovery. Illustrations.
