I own them all and just love the characters and I have learned more about quilting that any author would imagine. It "seams" so easy to just read about it and find that it enters my store of quilting knowledge.
Some books in the series are better or more... well better, but all are enjoyable. I listen to them on CD and read them too over and over again. Those gals and a few of the men folk have become my friends. Some you like, some you think are off their rocker but that is just the way it is with friends, isn't it.
