It would depend what "it" is. The sentence sounds incomplete to me and that makes it a bit unnatural when it is taken out of context. There are ways to use "in my book" to mean "in my opinion" but to make it sound natural you need to add what it is that you mean. Example: "In my book, there is no place for ____" Hope that helps.

yes it is natural.but also it is true : There is no place in my book
