The Moomins
Moomin! I enjoyed the first five books of course but the last four are especially sublime. I love children’s stories with an element of somberness, which Moominpappa at Sea and Moominvalley in November deliver in spades, to the point where I’ve heard some people question whether they can still be considered kids books at all… the answer to which is of course yes! Children’s literature that doesn’t make a child feel and think is the equivalent of junk food IMO, and I don’t think it’s any mistake that all the books/movies/comics I enjoyed as a child I can/do still enjoy, as an adult, today.
Also Snufkin. Who doesn’t love Snufkin?
“No book is really worth reading at the age of ten which is not equally (and often far more) worth reading at the age of fifty.” – Cs Lewis
Also snufkin is the best ever ever ever ever
