This book reminded me why I don't read many cozy mysteries. Many are published and a few I find satisfying as escape reads, but this isn't one of them. Not only was the story somewhat predictable because there were no other options, but this is not a book to read because you love knitting. The author admits she is a novice knitter, but it seems she doesn't even ask other knitters, look at books about knitting or even the internet to inform her writing. When she described knitting a swatch, she calls it "knitting a gauge" and includes a definition which was the only way I was sure she was talking about a swatch. Jeez. Doesn't she know anyone who knits?
The characters are not very interesting. The shop owner could be, but there are few details about her (she got divorced, moved, and opened a yarn store). Of course, most of those details would probably be about her shop and knitting, which the writer doesn't know, so she leaves them out.
As a knitter, I feel exploited by a writer who obviously picked this theme - yarn store owner- to sell mediocre books. I also am not a fan of padding the book with recipes and patterns added at the end as if readers don't have these readily available to them. So many publishers do that now that readers should let them know if they think they are gratuitous padding.
There are also misspellings of ordinary words, making me think she dictates and doesn't write. Or her editor (if there is one) doesn't know how to spell. Overall annoying and probably not worth your time.
