Query: Sometimes you wonder why you keep reading...

It's because you've read most of this author's previous works, in various formats, from the mysteries, to historical and even the lesbian leaning. And liked them.But this was a huge disappointment. Although most probably, I would agree with Ms. Brown's political leanings and share in her fears of biological warfare, if I wanted a lecture, I'd attend one. If I needed to reinforce my paranoia, I'd read non-fiction. But I read to be entertained, and this was not entertaining. I read to escape those very things she hit me over the head with. Yes, books should make you think, but if she wants to enter that arena, she needs to re-market herself.I wanted a mystery. The only one I got was trying to figure out why in the world I kept reading this book to the finish.
