Promise: A Tale of Sisterhood, Secrets, and the Shadows of Destiny

by Beth Ball

Before the assassin. Before the mask.
There was a promise made in blood.

Natalya has always been careful—silent steps, hidden magic, a sister to protect. But in the city of Serrana, danger cloaks itself in civility and strikes behind closed doors.

When Piper vanishes, Natalya must abandon the guild that's shaped her to rescue the only family she has left.

Armed with her magic daggers and a cursed ring, the fae will stop at nothing to see Piper freed, even if it means descending into darkness alone.

For Natalya, this is the moment she stops running.
For her enemies, it's the moment she becomes the Blade.



Promise is a dark, lyrical novella about sisterhood, sacrifice, and seizing inner power rather than asking for permission. It’s the soul-gripping prelude to Phantom, Book One of the Heir of Lilith trilogy.

“Little blade.” I’m a sucker for a good nickname.

Promise is a novella set in a dark world that somehow manages to pack more character growth into its pages than most full-length novels do. As a prequel, it’s absolutely doing its job: it sets the tone, teases the world, and left me itching to dive into Phantom.

The pacing is fast, as you'd expect from something this short, but it never felt shallow. Natalya is compelling from the jump; her inner conflict and her fierce love for her sister were palpable. It’s rare to find this much depth in so few pages. The emotional stakes are real, the world feels lived in, and the Ball clearly knows how to balance high-stakes tension with strong character moments.

If you're looking for a prequel that actually adds something rather than just padding lore, this one’s for you.

Thanks to the author for the complimentary copy. This review is voluntary and all opinions are my own.

I normally don’t read fantasy, but this was a book club choice. It is a novella, so I could say it was short and sweet. Only, it wasn’t short and sweet. It’s filled with violence, treachery, and murder. A fast-paced action-adventure story involving one sister trying to save the other from an evil villain. It moves along at a brisk clip. The book is intended as a lead-in or prequel to another series. There was some background information that I might have missed, having not read the rest of the series. But there was enough information to keep me engaged with the stories and care about the characters. An enjoyable story. If you’re a fan of high fantasy, this book is for you.

This was such a quick and fun read! I’m a sucker for a prequel novella because I love getting a little bit of backstory to some of our characters from whatever the main series is. This was no exception!

I really loved getting the glimpse of who Natalya is and why she is the way she is before we get to the start of Phantom - Book 1 in the Heir of Lilith series.

I’m diving into my ARC of Phantom now before release day on June 10th! Thank you so much to Beth Ball for the gifted ARC of Promise as well! 💜

This was a great prequel novella. I loved getting to read about Natalya and Piper’s story prior to meeting Natalya in Phantom. This was a great backstory and well written. This book has lots of action and great characters!

Short little novella. Not enough time to really develop characters, but I'm invested enough that I'm going to read Phantom.
