A children's book about an orphan, Maria Merryweather, sent off into a countryside valley, with her governess and her pet dog.
Her guardian makes her welcome and talks about the moon Merryweathers, such as Maria, and the sun ones, such as himself.
She finds a world of marvelous quirks and oddities, and also a tragic backstory, and a good deal of what is clearly magic, however lightly laid on. There are the Men from the Dark Wood, a necklace of pearls that vanished, a tawny dog, a wedding gown a woman never wore because she married someone else, books of poems and more. For a book with so much death, greed, and treachery in the back story, it's remarkably light.
