"I just finished reading this book and seriously can't wait for the next one! It was so witty, sarcastic and raw! I loved the in-your-face character flaws of the FMC and felt like at times she was my spirit animal! Two thumbs way up for this book!"

The Book You Didn't Know You Were Looking For

Part dark romance. Part noir. All obsession.

Part Dark Romance

It has the heavy and dark themes of the genre, but wasn't written to a Trope Checklist. It has spice, but that isn't the entire point. Instead, it's about a morally grey FMC coming apart and it feels uncomfortably real.

Part Noir

It's a mood that lands right away and doesn't leave. Think rain-soaked Seattle, cynicism, and a traumatized morally grey FMC that's obsessed with revenge and doesn't try to walk back any of her choices.

Part Something Else Entirely

She doesn't need him to save her, because she's the dangerous one. It isn't about his obsession with her, rather her obsession with revenge. Memento Sanguis doesn't fit cleanly into any genre, and that's the point.

Frequently Asked Questions

You have questions. I have answers.

What genre does Seraphina Black write?

TBH, it wasn't written to fit a specific section on a shelf.

But it has elements of dark romance as well as some noir and suspense. We're talking morally grey characters (particularly the FMC), slow-burn tension, and settings that feel like the city itself has a pulse.
This series is an 18+ trilogy for readers who like their stories on the darker side.

Short version: part dark romance, part noir, all obsession (hers, not his).

Is this dark romance?

Yes, in the general sense that matters. The themes are heavy, the FMC goes places and doesn't walk back her choices.
But, if by dark romance you mean a captor, a stalker, or a mafia boss, then no, this isn't that book. The darkness here is the world, the events, the trauma, and her. It's the revenge, not the relationship.

So what about the MMC?

He's not soft, insecure, or obsessive. He's actually one of the only steady things in the story.
He's a guy who sees what she needs, doesn't try to stop her, and definitely doesn't leave.
If you've been waiting for that guy to show up in a darker book, he's here.

Is Memento Sanguis a standalone or part of a series?

It's Book One of The Memento Series, which is a trilogy.
Each book builds on the last, so reading order will matter.
