The Exit by Helen FitzGerald
Some people love goodbyes... 23-year-old Catherine is mainly interested in Facebook and flirting, but she reluctantly takes a job at a local care home after her mother puts her foot down - and soon discovers that her new workplace contains many secrets. One of the residents at the home, 82-year-old Rose, is convinced that something sinister is going on in Room 7 and that her own life is under threat. But Rose has dementia - so what does she actually know, and who would believe her anyway? As Catherine starts investigating Rose's allegations, terrible revelations surface about everyone involved. Can Catherine find out what's really going on before it's too late?
