Query: what a disappointment

I've been a Patricia Cornwell fan for years, and have rated all her other books with 4 & 5 stars. I also have a personal rule that I give every book 10% of its pages to hook me. Being a Cornwell fan, I struggled through this book for more than 20% of its page total, but final gave up at the end of page 96. Nothing hangs together, the prose and action is totally contrived, and as a fan, I'm feeling ripped off. If you're a dedicated Cornwell fan, wait for the paperback or buy used, or trust me and skip this one altogether. Here's hoping she gets back on track with the next offering.
