Mayhem in Myrtle Beach — T. Lynn Ocean

Sherwood, a recent college grad with an accounting degree, is desperate for a job. But she hates numbers and wants to do anything but accounting. After moving to Virginia, she applies for an activities job at the Great Wings retirement community â€" even though her qualifications are nonexistent. Against all logic, the director hires Sherwood, pending a week-long trial period.
Jane Sullivan has a group of forty-six seniors heading to Myrtle Beach, South Carolina for a bus tour and they need a group leader. Sherwood happily accepts, thinking that it will be like a free vacation. After all, she told the director, seniors are no different than anyone else. They're just older.
But Sherwood's visions of bliss vanish when she realizes she's in over her head. Her group is eccentric and demanding. One of them goes missing. And to complicate things, the bus driver turns out to be a college study buddy who has lost the nerdy glasses and now looks totally hot in his uniform.
