A Man Called Ove, Fredrik Backman, Sceptre.
At first sight, Ove is almost certainly the grumpiest man you will ever meet. He thinks himself surrounded by idiots - neighbours who can't reverse a trailer properly, joggers, shop assistants who talk in code, and the perpetrators of the vicious coup d'etat that ousted him as Chairman of the Residents' Association. He will persist in making his daily inspection rounds of the local streets.
