The Dunlap's bed and breakfast is finally ready for the grand opening--or is it?--in this fourth book of a chapter book series inspired by Marguerite Henry's Misty of Chincoteague. It's time for the grand opening of Misty's Inn and Willa and Ben have been on their best behavior helping their parents get everything in tip-top shape! But they're tired of being up to their ears in lumpy mattresses and dust bunnies. Willa and Ben would much rather be helping their Grandma Edna reunite a foal with its missing mother. But as one disaster after another keeps happening at the Inn, the Dunlaps begin to worry that maybe running a bed and breakfast wasn't such a great idea after all. Will the Dunlaps be able to get everything ready in time, or will their dreams of running a successful inn disappear like the horse they're trying to save?
