Query: Just didn't do it for me

I bought 20+ books in this series not knowing much about them but after reading all the reviews thought they would be terrific. I found this book to be slow and not as futuristic as I was hoping for, although there is a lot of sex and sex crimes. I have started the second book and find myself putting it down looking for something else to read. Looks like it will take me a long time to get through all those books I purchased.
