Guarded by the Spider: A Dark, Steamy Monster Romance That Will Entangle Your Heart

What if the only thing standing between you and death… was a monster who could unravel you—body, mind, and soul?

Cassie Alexander’s Guarded by the Spider (Monster Security Agency) is a thrilling dive into the heart of monster romance, blending pulse-pounding suspense with erotic tension and emotional depth. This isn’t your standard bodyguard romance—unless your idea of the standard includes a deadly, seductive spider shifter with too many limbs, too many secrets, and just enough softness to break you.

At a time when the romance genre is craving bolder stories—ones that dare to look past traditional “beauty and beast” boundaries—Guarded by the Spider delivers a fantasy that feels both fresh and feral. It’s about what happens when you stop running from the monsters… and start wondering what it might feel like to belong to one.

A monster bodyguard. A woman on the run. And a connection too tangled to escape.

When our heroine finds herself hunted, desperate, and backed into a corner by something far worse than nightmares, she turns to the Monster Security Agency. This mysterious organization protects humans from threats they don’t even know exist. Enter her assigned guardian: Kass, a spider shifter with eyes that see too much and a body made for both danger and temptation.

Kass isn’t just a protector—he’s a predator. But unlike the ones chasing her, his instincts are tempered by loyalty… and something deeper, something he never expected: longing. As the two are forced into close quarters, the lines between client and guardian blur. Their dynamic is laced with trust, tension, and the kind of desire that coils tight like silk around the spine.

But monsters have pasts. And secrets. And the only way out of the web they’re caught in might be through surrender—of power, of pain, and of fear.

This isn’t a fairy tale. It’s something darker and far more intimate.

A heroine who fights, even when she’s terrified

She’s not a warrior, not a chosen one. She’s real—with fears, trauma, and instincts that have kept her alive this long. But what makes her compelling isn’t how loud she screams—it’s how quietly she survives. And how fiercely she starts to want something more.

A monster who learns to soften

Kass has more than eight limbs and razor instincts. He’s layered. Dangerous, yes—but also curious, protective, and so used to being feared that he’s completely disarmed by someone who sees him. His journey from detached killer to emotionally vulnerable partner is the book’s emotional spine.

Sensuality that’s strange, bold, and deeply connective

This is a monster romance. And Cassie Alexander doesn’t water it down. The intimacy between Kass and the heroine is alien, intense, and incredibly tender. She leans into what makes monster romance different: the exploration of unfamiliar forms, the trust required in surrender, and the undeniable beauty of bodies built to protect, not just pleasure.
