The Dunlaps prepare to host a respected travel writer during the busiest time of the year in this sixth book of a chapter book series inspired by Marguerite Henry's Misty of Chincoteague.

It's the week of the annual pony swim and Willa and Ben are excited! Misty Inn is fully booked for the days leading up to the swim and the auction of the foals, which takes place the following day. As if the island's biggest event isn't exciting enough, the Dunlaps get news that a travel critic/writer will be staying at the inn during that week. The kids are determined to show the special guest just how nice Misty Inn can be, but will they be able to prove it when they don't even know who the critic is?
