The book is good, however it's hard to get your hands into the book. I bought all of her books at once. However, they have great ideas and techniques. For people who love flowers, this book has some good information. It's definitely a better read then the other books in my line that I've read. Enjoy! Happy Holidays!

Good Review

This product works great with my Sony NEX 5.I was a bit disappointed when the first adapter that was sent to me didn't fit at all. You are supposed to insert batteries through little holes, and as soon as it snaps in place, you're suppose to twist or pull back so the battery will make contact. The holes looked too small for me, but if you force them in with enough force, they snap into place. But now that I've got this one right, it's pretty sturdy.

I have been a big fan of Nora Roberts for many years. But this was not good. There wasn't enough humor or charm to make it readable. The characters were one dimensional and the dialog didn't ring true. It made me cringe, especially about half way through. A disappointment from someone that has produced so much. This is definitely her worst effort.
