Query: What a disappointment!

I read the three previous novels of this author and loved them. Impossible to believe the same author wrote this one.I suspect Robert Ludlum ghosted it. Convoluted. A significant portion of the story takes place in the protagonist's mind.Little action. Little suspense. Morality big here - like Grisham, the author decided it was time for to write about the homeless. You can pass this one!
