Description

[April 2025 Writathon Winner]

In a land of sleeping spirits, an orphan escapes death by embracing Sin—now he must find a way out of her shadow.

In medieval Luskaine, the spirits of the dead sleep beneath the earth, and Jacob is about to join them. At the last moment, he’s saved, plucked from danger and poverty by his mysterious benefactor: the Lady Sin. Sin is many things: a mage, a warrior, and an unabashed murderer.

Hungry for power and desperate for control, Jacob devotes himself to following in her footsteps. After ten years of brutal training, he’s on the brink of achieving everything he’s ever dreamed of—until he uncovers a secret about Sin that shatters the foundations of his world.

Forced from his home and fleeing the very woman who made him, Jacob must learn to live without Sin before his past catches up with him.

The Last Sinis an epic story of self-discovery, combining fantasy action with page-turning suspense to keep you hooked until the last page.

Read Chapter One

What to Expect: (Updated: 1/10/2026)

Villainous Mentor:Jacob's time with Sin brings out the worst in him. His journey is equal parts learning to find his way and unlearning his past.

Plans within Plans:The Abyssal Lands is filled with schemers and power brokers. Their differing agendas advance and clash, often outside of our main character's point of view. Expect mystery, intrigue and betrayal.

Hard Magic:Magic is baked into the history of the world and its' people. As the series progresses, you will be introduced to the world's three distinct magic systems.

Every Fight Scene a Story:Fight scenes are choreographed in detail, drawing inspiration from real-life armed and unarmed martial arts.

Dialogue Heavy:The Last Sin is written in the first person point of view. You learn about the world as Jacob does, and our point of view as readers is shaped by his biases for better or worse.

Relationship Realism:The Last Sin contains relationships (both platonic and romantic) that are complicated, messy, and drive character development.

    As a huge fan of both spy books and fantasy, I was thrilled to learn about this story. No spoilers, but I just got to say that the writing is superb, the world building is perfectly balanced, and the plot advances at a smart pace. In our world, spy literature is a forgotten genre and fantasy is over exposed, but JustyceWrites get it done right on both accounts. Looking forward to more!

    Howling dogs. Orange flame cutting through the darkness. A shower of blood. Huehuehuehehe
    It's so atmospheric and grimy and immersive. So was the fear: A pebble biting into the knee, salty tears, metallic blood, it all makes the fear palpable.
    I love that you have an active protagonist, but in a passive moment. He wants to lay down and die. His hope is gone, his soul can't take any more darkness. But then this woman in red shows up with moon pieces and a veil and stuff like an arc of blood cutting through ceiling tiles (not just splashing them) and you get a wonderful intro explaining this world and the power levels of different entities in it.
    All of this to say this was a master class in what they call "Show, don't tell" writing.
    Here are my three favorite tropes happening here:
    The comfort character. Jacob is the guy who suffers relentlessly. He's abandoned, starving, hunted, forced to betray his best friend... we're on his side because we just want to give him a hug, and see him get one break.
    Blood Knight: The way The Woman in Red fights with grace, giggles about teaching violence, seems to treat combat like a dance... it's such a great contrast to Jacob who's terrified and wants to be a student.
    "An offer you can't refuse". That was a great high-pressure life-altering decision moment. We readers all wanna turn the page QUICK and see what happens next.

    ★★★★ 4.0
    Going straight to the point: The ideas here are great, the magic system basis is quite unique, the character are well written, and the world is well fleshed-out throughout the whole thing. This is great.
    Narratively speaking I finished the Cursed Lands, and the story direction from start to said end is questionable.
    I will keep the review spoiler free, specially because I do encourage you to read it (I know that 4 stars gets a bad rep here, but people toss 5s as if it was nothing, 4 is good!), but I will comment on a few points. The expectation of a spy thriller with an antihero is a bit oversold, we do have some elements of infiltration and misdirection, and I do believe we will have more in the future, but even after reading through the Cursed Lands we don't have that much of it. The antihero point has great structure, but poor Jacob isn't an antihero, he has clear indications of a hero with no other choice. It's a great struggle (and one quite well written), but more on the heavy conflict side than the antihero side.
    Style: Great style, from description and world-building, to well crafted fights! If I am to critique: the magic systems, although unique in the basis, are more means to classic magic than a real system per se. Far from a issue, but a dent in greatness.
    Grammar: If I don't remember something bothering me, it's 5 stars. If there were any small mistake, I didn't give it much thought.
    Characters: Great characters! Through and through. The supporting cast is amazingly real, antagonists have substance, and their drives and means are well defined. Poor Jacob is dealing with so much that our protagonist himself is (even if just a bit) one of the lesser ones in this category. His development seems to happen in larger steps than usual, reducing (in my opinion) the great impact the author was capable of imprinting on us.
    Story: Now, here's what made me leave this one behind, at least until a lot more is released and I can see the teased parts of the story that

    ★★★ 3.0
    This is at the end of Book One or maybe Part One in a traditional novel.
    TL;DR – All the stuff in the ‘what to expect’ section? Don’t expect it in the first 16 chapters. Ignoring expectations, strong start which whimpers out, with weak characters. Good enough to stay on your read later list, maybe push it near the back though. 3/5 feels too harsh but 3.5/5 too generous.
    The author’s description has written cheques his writing can’t pay yet.
    Let’s go for the positives – it’s a solid start to a normal fantasy novel where a young orphan gets taken in by a mysterious benefactor, gets trained up and then a twist occurs. The twist should be obvious as it’s listed in the description.
    The description kind of ruins the strongest emotional moments of these early chapters as it reveals what happens. BTW, the initial description sums up the first 16 chapters. I can’t summarise the story better than it can.
    Up to now, only a few expectations have been fulfilled.
    Spy thriller? No – the word misdirection has been used maybe twice. Actual espionage? No. Where I’m at, it looks like it’s going into a standard ‘party travels to do a difficult quest for big money’ storyline, not a spy thriller.
    Magic systems – not encountered yet. I know magic exists.
    An Anti-Hero? Maybe in the loosest terms and the MC Jacob did the worst things morally in the first chapter when he was a desperate eight year old kid.
    Fight scenes? Those are solid. The very few I’ve seen have been good if closer to anime style than real martial arts.
    Dialogue Heavy – Yes, at the expense of description. I’ll expand in style.
    Romantic Suspense – Not so far. There is a relationship – spoilers:
    Jacob has the interest of two twins in Sin’s household. They’re introduced when they’re eight, and then there’s a ten year time skip, where Jacob has messed around with both, has picked one to bed, travel with and even marry before it’s all ruined.
    Emotionally complex and messy? No. Drives motivation – like any dead girlfriend would.
