Review: Icon and Inferno by Marie Lu
Set a year after Stars and Smoke, this sequel follows Winter and Sydney’s reunion as they are tasked with a new and dangerous mission—rescuing another agent, who happens to be Sydney’s ex. However, when they arrive in Singapore, the situation is more complex than they imagined, and they quickly find themselves caught in a high-stakes assassination plot. With targets on their own backs and their own complicated feelings about each other to unpack, Winter and Sydney must find a way to save not only a life but also the world from a potential war.
❀ Entertaining Characters
I adore both Winter and Sydney, and it is so entertaining to read about them as a team. Like the first book, I find the balance between them with their different lifestyles—one in the spotlight and one in the shadows—so fascinating. This instalment dives deeper into their pasts and vulnerabilities, and I enjoyed getting to see so much character development.
❀ Action-Packed Story
As a story about secret agents, this one really delivers on the action. It is so thrilling to read about the characters’ strategies to gain information as well as their clever escapes when things get out of hand, and I particularly enjoyed the way they use Winter’s star power to find a way out of difficult situations. All of this makes for an entertaining read that kept me on the edge of my seat from the first page.
❀ Perfect for Thriller Fans
Icon and Inferno by Marie Lu is an action-packed spy novel that is perfect for fans of the YA mystery/ thriller genre. I loved the main characters’ dynamic, and I found myself completely immersed in the story. I hope to see a third instalment in this unique series in the future!

Great review, Olivia! It’s always nice to see when a sequel works out because that doesn’t always happen. I haven’t read these books (yet) but I do like the sound of them. Can’t go wrong with a good spy thriller!
