Query: Darker and Darker

I've mostly enjoyed the Alphabet series, but Sue Grafton's last few books have been darker and darker. I'm tired of the same old whining about her love life, her family, and her relationships in general. Her writing has become contrived, predictable, and frankly down right boring. I usually keep all my books, hardbound or paperback, but Q is for Quarry is going straight to my public library as a donation.
