School's out, so Phoebe and her unicorn best friend, Marigold Heavenly Nostrils, have the entire summer to play games, visit the pool, and even go camping. Unicorn horns are excellent utensils for roasting things over the campfire, too, even if Marigold prefers toasted apples to s'mores. It's all part of the unforgettable experience of Camping with Unicorns.
