Very well written . Anthony has overdone himself . The story is so captivating and the way he describes the locations and the details makes me feel not am really there . I love the Alex Rider series and I am looking forward to this great author next book .

A great story of Yassen and why he is who he is. This is a must read book

I loved the beginning lots because it didn't seem like the typical Alex rider book because you weren't expecting whats going to happen next. In the other books the plot was more straight forward with Alex rider getting trapped and the miraculously escaping. Also, the end had lots of twists and turns as well. This book is one of the best I've ever read! READ THIS BOOK!

This was a very thrilling and exciting book to read and I enjoyed it very much. It gave an interesting background into the life of yassen gregoravich and how he became what he was. I give it a five out of five. It was one of my favorites in the series.

This book was amazing! I hope he continues the series even further! That would be amazing!

This book was amazing and kept me on the edge of my seat all the way

👍

Loved the other books can't wait for this one

I didn't even scream this loud when they made remixes of one directions Best Song Ever! I'm counting the days till this comes out! Thank you Mr.Horowitz!
