Moominpappa at Sea

What do I say about this book? I'm not sure I understood a lot of it. Who, for example, is Little My and how did she get into Moominpappa's family? What exactly are Moominpappa and Moominmamma? Not that any of these questions really matter. I loved the book even though I didn't completely get it. I like books I don't quite get. I like the characters and I liked the author's penchant for slight digression into philosophical thoughts here and there. I've never seen anything about this series, and why is that? Why aren't more good, if somewhat out-there, books from other countries available in the US? Ah, questions, questions, questions.
