There's no news on early reviews of her new novel as far as I know. It could be that it's too early in the release process for reviews to start popping up, or perhaps it hasn't been widely distributed for reviewers to get their hands on it yet.
I'm not sure specifically which new novel by Ruth Jones you're referring to. She might explore various themes like relationships, family, or social issues in it.
Since we don't know the name of her new novel, it's difficult to say if there are reviews available. Reviews usually start to come out once a book is released or close to its release date.
I'm not sure if there are any 'new' ones that have surpassed the classics. But sometimes new novels can offer different takes. For example, some might explore Indiana Jones in different historical periods that haven't been fully covered in the movies.
Since we don't even know if there is a new novel yet, it's hard to say what to expect. But if it's like her previous works, it might have elements of food, memoir, and vivid descriptions of people and places.
