Not all guests know when to check out... A young waitress at a country hotel finds herself with a decades' old mystery to solve - one she hopes will help rid the hotel of its most troublesome guests. Its ghosts. When Ballinadrum Hotel's elderly owner Donahue Byrnes dies, twenty-two-year-old Mia Anne Moran discovers the spectral rumours that have long plagued the place are all too true. Meanwhile, Donahue's son, Cormac, wants to sell up as soon as possible but finds his plans thwarted by the ghostly goings on. Propelled by the belief that Donahue Byrnes intended to entrust her with the task, Mia strikes a deal with Cormac. She will act as concierge to the dead - keeping the hotel's ghosts in line, as Donahue did previously - and in return, Cormac will sell the business in its entirety, ensuring the future of both the building and its employees. But what drew Mia's errant charges to Ballinadrum Hotel in the first place? If she can work out that, she might be able to send them on their way at last. Life is rarely straightforward though - especially when it involves the dead - and as Mia tries to solve the hotel's ghostly conundrum, she begins to find hers changed in ways she couldn't have anticipated...
