I enjoyed it very much too. I also like Mary Kruger's series (Dyed in the Wool and Knit Fast Die Young), and Maggie Sefton's too (Knit One Kill Two, Needled To Death, A Deadly Yarn, and A Killer Stitch).
I also read The Knitting Circle and it's good too.
Wow, have I read EVERY novel about knitting? Not yet, I still have Debbie Macomber's series (The Shop on Blossom Street, etc) and Knitting: A Novel to go. LOL
