For fans of One Dark Window and T. Kingfisher, comes a standalone romantasy debut about a woman who accidentally awakens the power to siphon magic from two phoenix skulls, binding her fate to a vengeful stranger and forcing them to navigate the devastating cost of their unbreakable bond.
In a sanctuary for magical creatures hidden deep within a valley, magic is born from the bones of extraordinary creatures. For generations, a privileged few have siphoned this magic by wearing the skulls of these creatures and wielding their power.
Adela spends her days meticulously preparing these skulls to be matched, ensuring the magic endures and the valley sustains. But when she discovers two phoenix skulls—creatures she had believed only legend—she can’t resist the pull of their dormant magic. Defying the warnings of her mentor, Adela awakens the skulls, unleashing a shockwave of power that throws the valley into chaos.
Meanwhile, determined novitiate Kian prepares for the upcoming matching ceremony, but harbors a he is only participating in order to destroy the magic of the skulls to avenge the death of his parents at the hands of this tradition of power.
As Adela and Kian’s fates intertwine in the matching hut, the connection between them grows deeper and the power of the phoenix skulls grows louder. An impulsive kiss seals their fate—to each other and each to one of the phoenix skull masks. As they grapple with the consequences of their powerful new magic, their fated connection becomes the key to either the valley’s salvation or its ultimate collapse.
Ruinous Creatures Review
This was such a heartwarming read. After reading one plot-heavy fantasy after another, Ruinous Creatures felt like the perfect palette cleanser. If you're a fan of T. Kingfisher or just looking for a cozy fantasy, this might be for you. It's also a standalone, so it's perfect if you don't want to commit to a series or be left on a cliffhanger.
Adela completely won me over as she breaks free from everything expected of her and finally embraces the adventurous side she's always wanted to explore. As someone in my early thirties, there was something really refreshing about reading from the perspective of a 33-year-old FMC who feels trapped in the life she thought she was destined for. It hit differently than the typical young adult fantasy heroine discovering her destiny.
The romance was spicy and the connection between Adela and Kian was instant. That certainly doesn't mean a lack of emotional connection and relationship growth. As the story unfolds, we get to watch them uncover each other's motivations, which parallels Adela's own awakening to the corruption within the religious orders as she experiences the world beyond her sheltered valley life. Kian and Adela's fated connection creates the perfect set up for romantic tension without shortchanging the emotional chemistry.
I have to be honest though, while I really loved the sweet story and the romance, there were moments I found myself craving more action or higher stakes. I felt like I needed more urgency to keep me going, especially when I got to the latter half of the book.
Overall, if you want a feel-good story with a fast moving romance, definitely pick this up! It also works as the perfect palette cleanser if you're looking for something to read in between heavier fantasies.
