Query: Disappointing to an Evanovich fan

I'm a big fan of Janet Evanovich and the Plum novels. I also usually enjoy C.J. Critt as a reader, but this one failed to capture my attention. Critt's reading made Sam Hooker more lecherous creep than sexy, though flawed, hero.I'm intrigued by the NASCAR concept and love that Barney is an engineer, but the formula isn't working. It seems like Evanovich did more research for Stephanie Plum's bounty hunter than she has on women in NASCAR, so it's harder to get into these books. There are also too many location changes, unlike the Plum novels, where Trenton, NJ almost becomes a character itself.As a fan, I know Janet Evanovich can do much better than this. The family business needs to drop this product line and stick with what they know.
