Calamity [and a Danish] by Blake Pierce

When London Rose, 33, is proposed to by her long-time boyfriend, she realizes she is facing a stable, predictable, pre-determined (and passionless) life. She freaks out and runs the other way—accepting instead a job across the Atlantic, as a tour-guide on a high-end European cruise line that travels through a country a day. London is searching for a more romantic, unscripted and exciting life that she feels sure exists out there somewhere.

London is elated: the European river towns are small, historic and charming. She gets to see a new port every night, gets to sample an endless array of new cuisine and meet a stream of interesting people. It is a traveler’s dream, and it is anything but predictable.

Book #5, CALAMITY (AND A DANISH), takes them to the stunning city of Copenhagen. London is thrilled to sail into the historic harbor of Nyhavn, with its colorful homes lining the harbor, and to visit a delicious pastry festival, where the country competes for the best Danish in Denmark. But when she has the bad fortune to discover a dead body, London’s dreams turn into a nightmare, leaving her little time to solve the crime herself—or else find herself imprisoned.
