A must-read for admirers of Maria Semple's Where'd You Go, Bernadette and Rachel Joyce's The Unlikely Pilgrimage of Harold Fry Anybody who has ever had a grandmother will be charmed and delighted by the latest book from the author of the internationally successful bestseller A Man Named Ove, which is both heartbreaking and humorous in equal measure. Each person can recall the aroma of their grandmother's home. The tales their grandma told them are all that everybody can recall. But does anyone recall their granny making out with the police? driving against the law? Being caught breaking into a zoo in the dead of night? In her nightgown, firing a paintball gun from a balcony? Elsa, who is seven, does. Some people could refer to Elsa's grandmother as quirky or even crazy. Elsa refers to her as a superhero. Moreover, grandmother's tales of knights, princesses, and dragons? and castles, are her superpower. Because, as Elsa is starting to learn, heroes and villains don't always exist in imaginary kingdoms; they could live just down the hallway. As Christmas draws near, even the best superhero grandmothers may have one or two things they'd like to apologise for. And, in the process, Elsa can have some breath-taking adventures of her own . . .
