Paradise Lodge by Nina Stibbe

This is the story of Lizzie Vogel, a 15 year old girl who finds herself working in an old people's home in Leicestershire in the 1970s. The place is in chaos and it's not really a suitable job for a schoolgirl: she'd only gone for the job because she wanted a new phase and it seemed too exhausting to commit to being a full-time girlfriend or a punk. Lizzie has some knowledge of old people (they're not suited to granary bread, and you mustn't compare them to toddlers) but she doesn't know there's a right way to get someone out of the bath, or what to do when someone dies. When a rival old people's home with better parking and daily chairobics threatens to take all their patients, Paradise Lodge's cast of staff and helpers, from the assertively shy Nurse who only communicates through little grunts to the son of the Chinese takeaway manager who's renowned for his erotic handholding techniques, have to come together to save the home before it's too late. From the bestselling author of Love, Nina comes a story of being very young, and very old, and the laughter, and the tears, in between.
