The forgotten guide to happiness / Sophie Jenkins.

"Sometimes, happiness can be found where you least expect it. Twenty-eight-year-old Lana Green has never been good at making friends. She’s perfectly happy to be left alone with her books. Or at least, that’s what she tells herself. Nancy Ellis Hall was once a celebrated writer. Now eighty, she lives alone in her North London house and thinks she’s doing just fine. But dementia is loosening Nancy’s grip on the world. When Lana and Nancy become unconventional house mates, their lives will change in ways they never expected. But can an unusual friendship rescue two women who don’t realise they need to be saved?" -- Provided by publisher.
