Which book is Alex Rider Season 3 based on?

When Alex Rider first started, we knew that we wouldn’t get the book stories from beginning to end. The first season was based on the second book and the second season was based on the fourth book. What about the third season?

The third and final season of Alex Rider drops on Freevee on Friday, April 5. The entire season drops as one, allowing for a huge binge-watch this weekend. You have time to read the book that it is based on, though.

In the third season, Alex will go up against Scorpia, the criminal organization that has seen some major changes and brought some major twists throughout the first two seasons. Alex just doesn’t know who he can trust in the British Government, though. It’s even harder when he learns that he has some sort of connection to both organizations.

Alex Rider Season 3 is based on the fifth book

The final season follows the fifth book in Anthony Horowitz’s series of novels. That one is titled “Scorpia,” which is sure to give away who the big threat is.

In the fifth book, Alex learns that his father may have actually been an assassin for the criminal organization. This organization wants Alex to join their side, and he is losing strength to fight against them.

Well, then he learns about an operation called “Invisible Sword.” This is set to cause the death of thousands of people, and Alex wants no part of that. He will need to go up against the terrorist organization. The question is whether he can do it.

This is the best book in the whole series, in my opinion. It has the perfect amount of action and storytelling, while also delivering on the dramatic moments. I'm so happy the show got a chance to develop this story.

The book certainly does a great job of bringing a climactic moment from the buildup of Scorpia up to this point. It makes sense to use it as the final season, and there should be a way to wrap up the storyline for the TV show.
