Query: Not as good as I expected

I was disappointed in both this book and #2. I read the first book, then bought all 3 thinking this would be a good series to read. The author should have condensed all 3 into 1 book. It would have been much better. I was bored to tears by the middle of the second book and continued to plough through the second and almost all of this book before I finally gave up in frustration and tedium. I wish I hadn't wasted my money on any of them. I will be reluctant to buy any books by this author in the future. I wish someone had warned me.
