What I'd say is, this book is stronger than her Loop d Loop book for knitting. Although I admired her aesthetic for the knitting Loop d Loop, there wasn't much to move me to knit things for myself, especially when you compare it to Norah Gaughn's Knitting Nature.
Ms Durham also gives little asides, as in, what inspired her to do X and Y, and there's a delightful yarn about her grandmother. She seemed as mad as Fat Tuesday, but a thrill to hang with.
I can't vouch for the clarity and ease of her chart following, so I don't know if there are any erratas to boot.
As a novice crocheter, I appreciate the fact that she has 'beginner', 'Intermediate' and 'Advanced' on her projects, so I know how much tears I'm going to spill.
I do hope this potted view of the book has helped you to decide if you want to get it or not!
