The Hamilton Assignment - Diana Xarissa - Bog

Edward and Janet are enjoying themselves in London when they get given their next assignment. This one sounds simple enough. All they need to do is get inside a museum after hours and exchange some buttons on display with another, seemingly identical set. Of course, nothing is as easy as it seems when it comes to top-secret assignments. There's only one hotel in the tiny Pennsylvania town where they're staying, and Janet and Edward haven't been there long before they discover that things aren't what they appear to be at the Craterstown Hotel. Can Janet and Edward get the buttons exchanged before the museum shuts for a two-year remodel? Can they work out what's really happening at the Craterstown Hotel? And does Janet truly want to ride a roller coaster for the first time?
