The book is entertaining and provides a nice glimpse into the life of a mother with small children who isn't fulfilled by only rearing her kids. I think that's a perspective that we don't acknowledge often enough, so I'm glad she included it so prominently.
"Nursery Crimes" is a mystery, but real mystery fans will be able to figure out who done it fairly early. That's not the book's main lure. I'd say that's the main character and her family. This is a good start to a series where the characters are as interesting as the crime...and that's my kind of series. I'll read another for sure.
