A Man Called Ove by Fredrik Backman

Ove is almost certainly the grumpiest man you will ever meet. He thinks himself surrounded by idiots - joggers, neighbours who can't reverse a trailer properly and shop assistants who talk in code. But isn't it rare, these days, to find such old-fashioned clarity of belief and deed? Such unswerving conviction about what the world should be, and a lifelong dedication to making it just so? In the end, you will see, there is something about Ove that is quite endearing. This book is available in paperback.
