Alright so here is my elaboration on The Naruto series if were a Trilogy of Books rather than an anime/manga series:

Book 1: The Demon Fox Shinobi
Things that would be the same from Part 1:
- The plot would be the same (Land of Waves Arc - Sasuke Retrieval Arc)
- Naruto would be the hyperactive knucklehead idiot in the beginning.
- Sasuke would still end up in the same place he was from the start of Part 1 to the end
- Sakura would still have a super crush on Sasuke at the beginning.
- Secondary characters would still have the same role as they did in the manga/anime.
- The Akatsutski tease throughout the story
Things that would be different from the anime/manga:
- Since it is a novel the story will open with a third person pov prologue regarding the Kurama attack on Konoha.
- Explain where Jiraiya was during Kurama's attack on the village and why he couldn't raise Naruto.
- The rest of the story will take place from Naruto's POV in First person.
- Showcase the Graduation Ceremony after the Mizuki incident.
- Have Sakura's parents present at the Graduation Ceremony.
- Hint more of Orochimaru throughout the story before he appears in the Chunin Exams
- Have more missions of Team 7 before the chunin exams to make the bond more believable.
- Unlike the anime/manga, have Naruto witness a glimpse of Sasuke going into his curse mark before passing out.
- Show that Sakura feels terror when Sasuke uses the curse mark for the first time, and have it that as a point where she starts feeling different about how she sees him.
- Like in Part 1 have Hinata role model Naruto, but drop a small hint that she likes him by having her cheeks turn red when he tells her to get some rest and she thanks him for supporting her during her battle against Neji. That is where you get Kiba telling Naruto that he'll watch over her as hint from his side that he likes her.
- After seeing how far Naruto has gone from the land of waves to the Chunin Exams, Sakura accepts Naruto's date as a point where she reveals to Naruto that he saw the same thing she did in the forest of death like in the manga. However, the other reason is because she opens up to Naruto throughout the story and discusses what she's going through to him for someone to understand. The big change here would be that Naruto shows up at Sakura's house where her parents tease her about having a great time before they go. Then the date ends with Naruto dropping her off home and Sakura thanking Naruto for understanding before he heads back home.
- Like in the anime/manga Sakura attempts to stop Sasuke from leaving the village, but have Naruto listen in from the sidelines since the story would be from his perspective. That is where Sakura reveals to Sasuke about her feelings towards him, but that didn't matter now and how he should stay because of their Camaraderie throughout the story. Of course when getting the chance she tries to stop him before Sasuke knocks her out, and Naruto before doing anything gets knocked out by one of the sound four ninja.
- The Promise of a Lifetime still happens, but is handled differently from Sakura's point of view. Instead of telling Naruto to bring Sasuke back to her, Sakura wishes Naruto good luck and tells him to bring back their teammate. Of course, Naruto still oblivious about Sakura change of feelings towards Sasuke tells her that he'll bring him Sasuke back to her.
- Similar with the ending Naruto fails to bring Sasuke back, and wakes up in the hospital only to have Sakura sitting by his side. Instead of still believing that He'll keep his promise to her about Sasuke, Naruto doesn't look her in the eye because he believes he let her down. At that moment, Sakura motivates him to try harder and just because he failed once doesn't mean he should abandon it, and by doing so Sakura reminds him of his ninja and never going back on his word. At the same time she reveals that next time Naruto won't have to do it alone.
That would probably be how Naruto would go as far as the story goes in a novel format through my eyes...

Book 2: The Grasp of Pain
Things that would be the same from Part 2 :
- The plot would be same as Part 2 (Kazekage Arc to Pain Arc)
- Orochimaru's death
- Sasuke vs Itachi
- Asuma's death
- Jiraiya's death
- The Pain Invasion
- Naruto still having a crush/ being love with Sakura
- Most of the NaruSaku moments still happen the same way they did in the anime/manga.
Things that would be different in Part 2:
- Showcase not just Naruto's maturity, but also the training he went through with Jiraiya like developing an earth style jutsu as well as making tactical decisions in terms of fighting, and a small glimpse of Sage Mode.
- Small subtle hints that Tobi is Obito Uchiha
- Sakura showcases a fear that Naruto will end up like Sasuke when it comes to his hatred towards the Akatsutski for hunting Jinchuriki after discovering that Gaara was captured.
- Like how Sakura was in Part one, Have Hinata still shy but show that she has a crush on Naruto, but make her quirky in conversations with friends and have her sort of embarassed when talking to Naruto by herself but not make her constantly pass out.
- When Naruto enters four tails for the first time at Tenchi Bridge, instead of having Sakura remember the promise to bring Sasuke back instead she gets reminded of the terror she felt when Sasuke awakened the curse mark for the first time. However it is revealed that she herself didn't stop Sasuke then but Team 10 and Team Three (Guy) stopped him while she sat by in fear. Instead, here Sakura makes an effort in stopping Naruto and succeeds. Also, Since the book is through Naruto's point of view show that he sees everyone as a threat when going four tails.
- Have Sai reveal to Naruto that he can tell Sakura feels something about Naruto, and how its really noticeable when mentioning it to Naruto, but of course he still believes she likes Sasuke and not him.
- Throughout the Rescuse Kazekage Mission and Team 7 Reunion Arc alongside the Kakazu and Hiden arc have Itachi shadow Naruto from the distance to see how he is progressing as a shinobi, and have Naruto feel like somebody is there but really isn't.
- Showcase more moments between Naruto and Jiraiya with Sakura, Kakshi and Tsunade watching from the side even have Kakashi join the training with Naruto from time to time.
- Hint Pain throughout the story.
- Hint more of the Rasenshuriken throughout the story
- Showcase Naruto on his freetime seeing Hinata and Hanabi spending time with each other, maybe even have Hinata call Naruto over to hangout with her and her sister or even with Kiba, Shino, Tenten, Rock Lee, Neji, etc.
- When Team 7 reunites Naruto, and Sakura attempt to fight Sasuke at Orochimaru's hideout only to escape thanks to the help of Kabuto and Orochimaru after reminding him about his revenge towards Itachi.
- All of Sasuke's journey are shown in a similar fashion in Harry Potter when Harry learns of the events that happened with Tom Riddle only it is shown via extracting the memory from messenger birds and placing them in a fountain of outcomes which projects what they've discovered. That is how Naruto and Sakura learn of Sasuke's whereabouts regarding Orochimaru and with his battle against Itachi.
- Like with The Sasuke situation, using the memory from Fukasaku via the fountain of outcomes that is how Naruto not only learns of Jiraiya's demise, but sees how it took place. Like in the anime/manga that is where Naruto vows to everyone present that He will avenge of Pervy Sage.
- Similar from the manga, Shikamaru and Iruka Sensei try to help Naruto, but also Sakura attempts to do something as well. She tries to be there for Naruto, and reminds him of the situation Sasuke got into when he wanted revenge, but he believes what Sasuke went through and what Naruto is going through is different. That would end off the conversation with Sakura slapping Naruto and telling him, "If you don't want my help then forget it."
- The Training to improve Sage Mode on Mount Myoboku happens the same way it does in the anime/manga, but showcasing Naruto's frustration in the training in the beginning before hearing from the Frog sage to relax on the training. However, Naruto decides to stick to his method because he believes that he'll be better in this mindset when it comes to Pain.
- Kakashi won't die.
- Shizune, and Choza will still remain dead as well as other casualties that took place.
- Tsunade would actually die at the end.
- When in his eighth tail mode, Minato and Kushina bring Naruto back to reality together and it is there where Kushina helps Naruto obtain the Chakra mode he has in the Chikara filler arc.
- After the battle with Pain does Naruto realize where his revenge against Pain has brought himself, and confronts him face to face. The conversation happens the same way it does, but instead of making the concept of peace Naruto's goal, He says "Peace is a difficult concept to make a reality because there will be always be a threat out there to prove what their doing is right". Those are the kind of people that Naruto vows to Nagato that he'll stop and will do whatever it takes to protect the village even if it means taking desperate measures. The conversation would end the same way in the manga/anime with Pain intrusting naruto of making the dream of becoming Hokage as well as speaking of how he sees things. Knowing that Nagato will die Naruto won't kill him or forgive him for what he's done to the village, but he won't save him either.
- Even though Naruto knows Hinata loves him before he went four tails, He says that he appreciates her however his heart belongs to someone else. Hinata despite being heart broken, smiles and tells Naruto to chase after Sakura and vows to do whatever it takes to win her heart. Of course this would be after the Pain fight!
- At the end near Sunset beginning of nightfall, Naruto apologizes to Sakura with the way he acted when they last talked, and like the anime/manga she whacks him on the head and embraces him with a hug saying "Thank you". While everyone cheers for Naruto for saving the village, Hanabi and Konahamaru point out about the slightly faded red moon in the sky and before they have a chance to say anything they find themselves within an alternate reality. That is how the story of Book 2 would end..
That would be how I'd picture Naruto going if it came to Naruto as a series of book even though it's just my ideas, and I will wrap up how all these things would be wrapped up in the final book of the trilogy Naruto Book 3: Semblence World after I get back from work......
