Romantasy has really taken off in recent years, with emerging authors coming through left and right, and even TikTok (BookTok) further boosting the genre’s popularity in 2025. Romantasy author Rebecca Yarros released a new Fourth Wing novel earlier this year, and it continues to sit at the top of pretty much every list of best-sellers for 2025 since then. And in the ebook space, that same series has dominated Amazon’s list of top-selling Kindle books with all three novels sitting in the top three spots. Considering those levels of popularity, it’s certainly not surprising that such a series would have an adaptation already in the works.
What is surprising is that an entirely new romantasy novel, yet to be released, already landed a movie deal. Alchemised is an upcoming book by SenLinYu that releases on September 23, but Legendary Pictures has reportedly paid more than $3 million for movie rights to the story before it’s even available to the public. This is most likely because the novel has roots in the world of Harry Potter fanfiction, which gives it the potential to pull in a big audience from an existing fantasy franchise. No matter the reason, this deal seems like a sign that the romantasy genre is starting to hit peak levels of interest. As an avid reader of romantasy myself, I certainly feel compelled enough by the news to give it a read and see what the hype is about.

If you’re intrigued by the premise of this book, or are just interested in what makes it worth a $3 million-dollar deal, you can pick up a copy pretty much everywhere right now at a discount. If you’re looking for an ebook version of the novel, Amazon has the Kindle version for only $14.99. Unfortunately since it’s a popular new release, you won’t be able to read it for free with a Kindle Unlimited subscription. Amazon also has physical copies of the hardcover edition at discount, which is also available at Barnes & Noble for $24.50. Barnes & Noble is the only place that has signed copies of the book available online for $35, so if you are looking for that version you’ll have to buy it there for full price.
What is Alchemised about?
For a quick look at what to expect from the story, you can check out the synopsis I grabbed directly from the book’s website.
“Once a promising alchemist, Helena Marino is now a prisoner—of war and of her own mind. Her Resistance friends and allies have been brutally murdered, her abilities suppressed, and the world she knew destroyed.
In the aftermath of a long war, Paladia’s new ruling class of corrupt guild families and depraved necromancers whose vile, undead creatures helped bring about their victory, holds Helena captive.
According to Resistance records, she was a healer of little importance within their ranks. But Helena has inexplicable memory loss of the months leading up to her capture, making her enemies wonder: Is she truly as insignificant as she appears, or are her lost memories hiding some vital piece of the Resistance’s final gambit?
To uncover the memories buried deep within her mind, Helena is sent to the High Reeve, one of the most powerful and ruthless necromancers in this new world. Trapped on his crumbling estate, Helena’s fight—to protect her lost history and to preserve the last remaining shreds of her former self—is just beginning. For her prison and captor have secrets of their own . . . secrets Helena must unearth, whatever the cost.”
