Gone girl, a best seller, is one of books in which I have a huge interest. I am interested in this book because it give me a new light about marriage and love. Once I take love for granted and I thought love is all about romantic fairs which is unconditional. But in this book I saw that the couple who want to manipulate each other in their marriage. So it attracted my interest. And I adore this book so much.

Notes

An interesting book I have read  ---  you could have written An interesting book that I have read. That is implied in your sentence. Many English writers would omit the word so this is just so that you are aware of it.

Gone Girl is the title of a book. You often see a book title written as Gone Girl   so that it stands out (the italic print is what you would see).

insight is the word that you needed rather than light -- light makes brighter, insight is about understanding and ideas.

took is the past tense of the verb  to take. It is one of the many irregular verbs in English, you were talking about the past, so use took rather than take.
