Jane I agree. One of the best things about the story was how unusual it was, so I Googled where the idea came from. On Wikipedia it says
She came up with the idea while on holiday in Amsterdam, where she viewed Petronella Oortman's doll house at the Rijksmuseum, and undertook extensive research on 17th-century Amsterdam, studying books, cookbooks, Dutch Golden Age paintings, maps, and wills.
Wikipedia gives quite a bit of information about the author and the book, including the fact that 11 publishers bid for the book and the winning bid was in six figures. What a triumph for a debut novel.
