Shikamaru is one of the best characters in Naruto, not just mine but a fan favorite. In this story, there is a jump to the future where Shikamaru is a chief advisor to the Hokage and must prevent a new war from breaking out. Of course, he is just as intelligent and witty as before, while being absent-minded and easily bored. Shikamaru is an excellent advisor, thinking several steps ahead, but is also a family man who unfortunately sacrifices time with his family in order to help Konoha.
I enjoyed this novel as a whole, but there is just something about the writing that makes it a bit dry for me. If you grew up with Naruto, I'm sure this will be a nice addition to your collection, but I wouldn't call it a must read.
