Goodreads Book Synopsis: In the land of the unforgiving desert, there isn't much a girl wouldn't do for a glass of water.  Twenty-four-year-old Saeris Fane is good at keeping secrets. No one knows about her strange powers, or the fact that she has been picking pockets and stealing from the Undying Queen's reservoirs for as long as she can remember.  But a secret is like a knot. Sooner or later, it is bound to come undone.  When Saeris comes face-to-face with Death himself, she inadvertently reopens a gateway between realms and is transported to a land of ice and snow. The Fae have always been the stuff of myth, legend, and nightmares... but it turns out they're real, and Saeris has landed herself in the middle of a centuries-long conflict that might just get her killed.  The first of her kind to tread the frozen mountains of Yvelia in over a thousand years, Saeris mistakenly binds herself to Kingfisher, a handsome Fae warrior with secrets and nefarious agendas of his own. He will use her Alchemist's magic to protect his people, no matter what it costs him . . . or her.  Death has a name. It is the Kingfisher of the Ajun Gate. His past is murky. His attitude stinks. And he's the only way Saeris is going to make it home. 
 
If you are a dark romance lover and if you’ve been craving a story that wraps danger in desire, blends raw chemistry with revenge-fueled secrets, and serves up an antihero who will ruin your standards forever, Quicksilver by Callie Hart is a must-add to your TBR.  From page one, this slow-burn, morally gray SPICY romance sinks its claws in. Here’s my deep dive into the chaos, passion, and gritty brilliance that is Quicksilver. 
 
“Do not touch the sword. Do not turn the key. Do not open the gate.”

Spoiler-Free Summary 
Saeris Fane is the reluctant heroine in this story.  She is the main female protagonist, a thief, later discovering that she is an alchemist.  She is fiercely independent, resourceful, and emotionally guarded.  Saeris begins as a survivalist thief in a brutal desert society, shaped by trauma and secrecy. Her journey is self-discovery as she learns about her true heritage and powers as an alchemist. She evolves from a lone wolf into a reluctant leader, learning to trust others and embrace her destiny.  She has many strengths.  She is quick-thinking, brave, and morally complex.  She is also flawed, distrustful, impulsive, and emotionally repressed.  Through this story, you get to read how Saeris goes through this transformation, both literal (alchemy) and emotional. Her control over Quicksilver mirrors her struggle to master her identity and emotions. 
 
Kingfisher is the fae warrior with secrets.  He is the main male character who will be Saeris’s love interest.  He is also a fae warrior and guardian of Yvelia.  He is extremely stoic, enigmatic, and fiercely loyal.  Kingfisher is initially cold and distant, bound by duty and haunted by past failures. His relationship with Saeris forces him to confront vulnerability and rediscover hope. He’s a classic “wounded protector” archetype with a slow-burn emotional thaw.  He has so many strengths, mainly his strategicness, power, and emotional intelligence.  Like Saeris, he is also flawed.  He is overly secretive, emotionally withdrawn, and burdened by guilt.  Kingfisher embodies the theme of death and rebirth—his icy realm and demeanor contrast with the warmth Saeris brings into his life. 
 
Spice Level: 4/5 
The sexual tension is slow and loaded with restraint, but once it hits? FIREWORKS. The scenes are passionate, raw, and emotionally charged. 
 
Final Overall Rating: 4.5/5 Stars 
If you like your romance intense, complex, and edged in shadows, Quicksilver delivers everything and more. It’s a haunting, seductive story about grief, vengeance, healing, and trust — told through two broken souls finding salvation in each other.  I cannot wait for book two to come out this November (18 November 2025 – “Brimestone”)
