Stirling engines are unique heat engines because of their theoretical efficiency is almost equal to the theoretical maximum efficiency,
Called the Carnot cycle efficiency. The Stirling engine is heated by gas expansion, cold contraction generate power.
Description:
Name:Stirling Engine Hot Air Model
Material:metal,glass
Color:gold
Size:165x87x95mm
Features:
-This is an external combustion engine in which the fuel is burned continuously, and the piston is moved by the expansion of air (or helium or hyd rogen) as a medium, and the expansion gas is cooled in the cold chamber, and the cycle is repeated. Only a small alcohol lamp, you can make it fast rotation and strong power.
-As the external combustion engine to avoid the traditional internal combustion engine of the explosion to do work, in order to achieve a high efficiency, low noise, low pollution and low operating costs.
-The biggest advantage of the external combustion engine output and efficiency from the influence of altitude, very suitable for high altitude areas.
- Aerodynamics are rich in knowledge of physics, single cylinder combustion engine. Engine principle is intuitive, educational toys, teaching experimental equipment can effectively cultivate children's interest in learning can also be used for classroom teaching, more intuitive and easy to understand.
Instructions:
-The engine model on the horizontal position by hand toggle the flywheel to see if smooth, if there is a strong sense of raw astringent, check the connection rod is normal, whether the cylinder oil and dust, and if so, please use toilet paper to erase Not smooth. Toggle the flywheel feel pressure rebound within the cylinder body is a normal phenomenon, the cylinder is sealed.
-The packing bag of alcohol lamp cotton wear into the metal cap lamp.
-Please go to the pharmacy to buy 95% purity alcohol, anhydrous industrial alcohol better. Fill the alcohol lamp to less than two-thirds.
-Alcohol lamp to the alcohol lamp, at the premise of ensuring safety, ignite the alcohol lamp about 2 minutes after the flywheel, until the flywheel automatic operation so far, the whole process of heating, hands may not touch.
-Led lights can be directly into the generator output interface, if not inserted, the exchange can be positive and negative, led a long foot for the cathode.
Note:
-There will be the operation of steam,when the steam too much time, the engine will stop working,
inside and outside the needle often set aside to reduce friction
-Do not rotate the nut too tightly, otherwise the glass is broken, if the piston is cracked,
can be bonded with glue.
-The alcohol lamp wick do not touch the glass, do not get too tight ring
-Pulling the piston connecting rod can not force the front end, because the front
end is easy to break
Package include:
1 x Stirling Engine
1 x Alcohol Burner

Very detailed! Beautiful world building! Strong Heroine!
Format: Kindle
Starts off a little slow and confusing with different POV’s, but starts to all come together towards the middle to make an elaborate plot line and makes it all worth it. Beautiful world building and attention to detail as well as great writing. The cliffhanger was gut wrenching! Can’t wait for the next book!

Interesting
Format: Kindle
This was a very captivating book once you got into it thoroughly. But the third person perspective was a bit hard to get used to. But as you got into it and followed the different characters, it was interesting and filled with intrigue, conflict and forbidden love.
I can’t wait to read the next one and to complete the series.

Just read it. You won’t regret it.
Format: Hardcover
This book completely blew me away. I loved every single character—not just the FMC and MMC, but the side characters too, which is rare. In a first book, side characters can feel flat while the focus is on world-building, but that definitely wasn’t the case here.
The romantic tension between the FMC and MMC was so good—seriously addictive. The plot itself felt pretty straightforward at first, and the world-building was easy to follow. It even gave me Heartless Hunter / Wolf King vibes… until the last 20 pages.
And wow—those final pages. I usually spot plot twists coming, and I thought this one was going to be predictable, but I was completely wrong. That ending genuinely shocked me—I haven’t had that reaction to a book in a long time.
I’m already counting down to book two (and that teaser chapter? Absolutely brutal).
Just read it. You won’t regret it.

4 Stars for Now!
Format: Kindle
I DEVOURED this book. I was in a huge slump after reading a horrible series right before this but after 3 pages of this book, I was hooked. I read the whole book in 2 days. I think the author did an amazing job at writing an engaging story with an amazing twist at the end. I know many readers feel betrayed by the twist and find the narrator to be unreliable but I feel that the twist was done in a great unsuspecting way. Though I do feel betrayed, I think there is so much room for redemption in the second book!
The author also did an amazing job at world/character building. She was able to do so without interrupting the story which is one of my huge pet peeves. A lot of authors build by taking breaks in the plot or dialogue which I find choppy and disengaging but this author was able to build in an engaging way. There was some lack of world/character building but I think that was due to keeping reader in the dark. The world, politics, and characters were all very easy to understand.
I found the romance a little lackluster and a bit off-kilter. Some of it was really pushy and rushed which left a bad taste in my mouth. I do hope the author delves deeper into the romance in coming books.
The FMC was a breath of fresh air. She was not whiny or stuck-up like most books. She was never afraid to accept help from others but she was still able to shine with her intelligence. Not once did I think she made a poor decision just for the sake of a plot point. She was really easy to like. The MMC could use some work but I think that will happen more in coming books.
This is a MUST read, my only advice would be to wait until it is a finished series!

Need book 2 please :-)
Format: Kindle
From the very first chapter, Metal Slinger hooked me and refused to let go.
Set in a brutal, metal-bound world where power is carved from steel and survival depends on strength, strategy, and sheer will, this story follows a young woman forced into a dangerous system where control over metal isn’t just magic — it’s dominance, protection, and rebellion. When she’s pulled into escalating conflict and shifting alliances, she quickly learns that power always comes with a cost.
The magic system is sharp and immersive without being overwhelming. The way metal manipulation is woven into combat and politics makes every confrontation feel cinematic and high-stakes. It’s gritty, tense, and beautifully layered.
The Brynn, our FMC absolutely shines. She’s fierce but not untouchable, resilient without feeling unrealistic. Watching her navigate betrayal, survival, and the slow awakening of her own strength felt earned every step of the way. There’s grit in her fight scenes and vulnerability in her quieter moments that make her deeply human.
And the tension? Immaculate. The chemistry simmers under the surface before sparking into something electric. Every reluctant alliance, every charged interaction, every moment of “are they about to destroy each other or kiss?” had me flying through pages.
The pacing is relentless — no filler, no wasted scenes. Twists land hard. Stakes keep climbing. And that ending? Absolutely feral. The kind that leaves you staring at the wall for a minute before immediately checking when book two releases.
✨ Gritty metal-based magic
⚔️ High-stakes survival
🔥 Slow-burn tension
🖤 Fierce, layered heroine
💥 A finale that HITS (but cliffhanger!)
This is one of those fantasies that reminds you why you fell in love with the genre in the first place. If this is just Book One, I am more than ready to be emotionally wrecked again in the sequel.
