The Incendiary by LJ Claren: A Slow Burn Sequel
Overall Rating: 5 Stars Spice Rating: 2.5
Disclosure: I received an advance review copy of The Incendiary by LJ Claren in exchange for an honest review. All opinions are my own.
If you were here last year, you already know how I feel about The Silversmith. It was my favorite read of 2025, full stop. So when I say I went into The Incendiary with a very specific kind of nervous energy, I mean it. The bar was set high. I needed this book to deliver.
It did. More than.

What Is The Incendiary About?
The Incendiary is the second book in LJ Claren's series that began with The Silversmith. If you have not read book one yet, I would stop here, get yourself a copy, and come back once you have recovered. This is a series best experienced in order, and The Silversmith lays the emotional groundwork that makes The Incendiary land as hard as it does. If you have already read it but need a refresher before diving into book two, I put together a full spoiler summary of The Silversmith that covers everything you need to know heading in.

Here is what the publisher has to say about The Incendiary:
They thought she was powerless. Now she is unstoppable. Everything that Ary thought she knew was a lie. She has been caged and controlled, lied to by the ones she loved. Now she is finally free, with untamed magic sparking in her veins. They say she is destined to lead an army against corrupted darkness. They say the man she loves is dangerous, that she will never see him again. But Ary is done listening to what they say. She will choose her own destiny. It's time for her to burn.

I am keeping this review intentionally light on plot details because The Incendiary is the kind of book that deserves to be read without too much prior knowledge. What I will say is that book two deepens everything that made book one so compelling.

Where The Silversmith Leaves Off
Mild spoilers for The Silversmith below. For the full detailed recap, head over to my complete spoiler summary of The Silversmith.
Book one ends with Ary standing in the wreckage of everything she thought she knew. Molochai tore out her heart. She survived it, which shifts what she is in this world in ways the story is only beginning to explore. She now knows who she truly is: a queen's daughter, over four hundred years old, carrying ancient magic in her blood, and Smyth's wife from a life she spent the entire first book not remembering.
She also knows what Smyth did. What the blood oath forced him to do. She sent him away.
Smyth left. He left her in the care of his cousin Damon, the one person he trusts above anyone else, and he left a letter. He will not return, he says, until he has found a way to break the oath. He is not abandoning her. He is trying to become someone who is no longer a threat to her.
Simeon, the man who organized the resistance and arranged Ary's entire life without her knowledge or consent, is missing. His absence is a significant problem heading into book two.
And then there is Elias. The final pages of The Silversmith give us our first real look at him as a person rather than a looming name, and he is furious. He has heard what happened. He is calling Gemma to him, clearly suspecting she knows more than she has shared.
The Incendiary picks up with all of that unresolved. Ary is alive, awake, and done being managed. That is exactly the setup this story needed.
The Flashbacks Add a Layer That Changes Everything
One of the things The Incendiary does particularly well is how it uses flashbacks to fill in Ary and Smyth's history. Book one keeps certain things just out of reach, which is part of what makes the tension work so well. Book two gives us that backstory, and it does not feel like an information dump. It feels like context that has been earned.
Watching Smyth's insta-love for Ary unfold in those early flashback moments is something I did not know I needed until I had it. It adds dimension to a dynamic that was already compelling and reframes a lot of what happens in the present timeline. By the time I understood where they started, I understood them completely.
LJ Claren's Writing Remains the Strongest Element of This Series
The Silversmith established that LJ Claren writes with real intention and precision. The Incendiary confirms that was not a one-book thing. The prose here is just as beautiful, maybe even more so because the emotional stakes are higher. She does not over-explain and she does not rush. Every scene is doing work.
Claren had promised readers an emotional experience going into this release, and she was not exaggerating. The Incendiary took me through joy, genuine anxiety, despair, shock, and more than a little hysteria, sometimes across only a few pages. That kind of range does not happen by accident. It is the result of writing that actually trusts the reader to feel things.
The Slow Burn Payoff Is Everything
I want to talk about this without saying too much, which is its own kind of challenge.
The Incendiary is the ultimate slow burn done right. If you have been patient through the tension of book one, book two rewards that patience in the most complete way I could have hoped for. The relationship between Ary and Smyth is given the space and the weight it deserves. Nothing feels rushed and nothing feels cheap.
That ending in particular is going to live in my head for a long time. It is bold and it is earned, and it is exactly where this story needed to go. That is where the hysteria came in. I have no notes.
Final Thoughts: Should You Read The Incendiary?
If you loved The Silversmith, the answer is yes, obviously, and you probably already knew that. But if you have been on the fence about starting this series, let this be your push. Book two is the sequel that confirms this is exactly the kind of series worth investing in from the beginning.
The Incendiary is everything I hoped it would be. Five stars, no hesitation.
