Murder [and Baklava] 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.

But when a wealthy, high-maintenance passenger suddenly turns up dead outside of Budapest, the cruise has become a bit too unpredictable. Even worse: as the last person to see her alive, suspicion falls on London, leaving her no choice but to solve the crime (with her new sidekick, an orphaned dog), and save her cruise line and herself.
