The Unicorns Who Saved Christmas by Mary Winn Heider

This is a slight, but funny Christmas story that would be a good choice for unicorn-obsessed kids this Christmas. When the reindeer come down with chicken pox, the North Pole Unicorn Troop is called into duty. They're the only other magical beings who might be able to pull the sleigh. With unicorns being "a little extra" all the way, they rise to the challenge. Good for a giggle, would hand only to kids who are big fans of unicorns (there are a lot of those kids around, tho!).
