Where have all the editors gone?

I'm currently reading a book loaned to me by a co-worker. I'm not really enjoying it all that much but I rarely put down a book once I've started one. Today I read the following where the authors are describing a character at a Pilates class:

Instead of sitting at home feeling sorry for herself, she's literally taking
her demons to the mat and fighting them off one after another.

Now I have to continue reading the book to find other glaring grammatical errors, because this book is not a Buffy the Vampire Slayer novel. Demons and ghouls are not characters in this novel.

Shame on the authors (James Patterson and Peter DeJonge) and shame on their editor and shame on the publisher of Beach Road.
