Where is the Midnight Sun? : View on the Secret Series, 1- 4

When reading," The Secret Series," by Pseudonymous Bosch, I realized that there's not a lot of conflict  with the Midnight Sun in the fourth book (This Isn't What It Looks Like)  then the last three books. Not until the end was there conflict with the Midnight Sun, however, it was kept to a minimum. What could this mean, I wonder. Simple, I believe that the last three books needed the conflict with the Midnight Sun in order to be interesting. Because otherwise, what would be the point in creating the series in the first place.

In the book," The Name Of This Book Is Secret", (Which is the first book) needed conflict with the Midnight Sun in order to lead on to the other two. It needed to create a conflict that went on throughout the series. In this book, the Midnight Sun created many dilemmas one after another for the protagonists to face. The Midnight Sun gave this book color, they gave the reader a reason to read on.

In the book," If Your Reading This, It's Too Late", (Which is the second book) the conflict with the Midnight Sun is needed because it continues from the first book and leads to the third book.

In the book," This Book Is Not Good For You", (Which is the third book) a whole new conflict with the Midnight Sun is created which leads to book four.

In the book," This Isn't What It Looks Like," (Which is the fourth book) conflict with the Midnight Sun is shown only towards the end. I think it's necessary for the first three books to have lots of conflict with them, but the fourth should have only a minority. I say this because the first three needed lots of conflict so the reader is kept happy, whilst the fourth is fine the way it is for the little amount of conflict projects much more than intended.

Not all books in a series have to have lots of conflict. When there is at least one book that challenges your mind and gets you to decipher many messages that are translucent, you don't need a book full of conflict. It's better to have a book that makes you think than to not have one at all.
