Query: Evanovich hits bottom

I have read the first eight Stephanie Plum novels ... and I loved every bit of them ... almost. Even though I am male, and the books' target audience is female, I found the first seven refreshing, hilarious, and full of appeal no matter what your gender. But in Hard Eight, Evanovich basically destroys her heroine's "likeability factor" -- big time -- by having Stephanie basically cheat on Morelli. Evanovich tries like hell to justify all of this ... but it rings hollow. I wonder if all of the female readers of this series would be so forgiving if it was Morelli cheating on Plum. The double standard is in full force here, and Evanovich just ruined a GREAT series by turning her heroine into a common slut, who cheats because she is motivated by nothing more than lust.
