These are ultimately happy novels:
Miss Benson's Beetle
by Rachel Joyce
about a spinster schoolteacher, Margery Benson, who abandons her life in 1950s London to search for a mythical golden beetle in New Caledonia^
Rachel Joyce also wrote
The Unlikely Pilgrimage of Harold Fry
...which is also quirky and funny.
about Harold who goes on a long journey
...neither of these is relentlessly humorous but both are ultimately "smiling' sort of books - but also with very funny parts.
I recommend these two books as well, in particular the Beetle one, it’s a really good and uplifting read.
