Tove Jansson's Moomin characters and books are admired the world over.

In the United States the series beginning with Finn Family Moomintroll (first published in English in 1945) has accumulated generations of fans.

Since Farrar, Straus and Giroux began reissuing the books in 1989, grateful readers old and new have been thrilled to have the stories available again.

At last the final installment is being published - oddly, the only book that features none of the Moomin family themselves, though it does take place at their house.

There familiar characters converge - Snufkin, the Hemulen, Fillyjonk, and others - seeking out the Moomins' welcoming company, only to find them absent.

All remain at the house, all have very different personalities that clash often, but something about their homey cohabitation during the icy winter changes each visitor in a gratifying way.

As The Times Literary Supplement put it, Moominvalley in November is "e;possibly the cleverest of the Moomin books."e;
