Book Review: The Diabolic (The Diabolic #1) by S.J. Kincaid



Nemesis is a Diabolic. Created to protect a galactic Senator’s daughter, Sidonia. The girl who has grown up by her side and who is as much as sister as a master. There’s no one Nemesis wouldn’t kill to keep her safe. But when the power-mad Emperor summons Sidonia to the galactic court as a hostage, there is only one way for Nemesis to protect Sidonia.

She must become her.

Now one of the galaxy’s most dangerous weapons is masquerading in a world of corruption and Nemesis has to hide her true abilities or risk everything. As the Empire begins to fracture and rebellion looms closer, Nemesis learns that there is something stronger than her deadly force: the one thing she’s been told she doesn’t have – humanity. And, amidst all the danger, action and intrigue, her humanity might be the only thing that can save her, Sidonia and the entire Empire…


I just KNEW I was going to adore this book although at first I was skeptical, “The Diabolic” managed to 100% win me over though with it’s utter perfection (or really it just contained everything I look for in a book and did it awesomely).

I really don’t have to much to complain about and thus will spend this review trying to convince YOU to read this book!


Also just one little side note here! This book WAS supposed to just be a standalone and apparently it is now a trilogy which is a little upsetting to me since I thought it was all wrapped up 100% and I’m not sure I’ll like it having more books now since the ending was completely satisfying. I’d also love to hear YOUR thoughts on this too so leave some comments down below!

Now before I start gushing about how amazing this book is I will start with saying this book takes a little patience at the beginning! When I first started reading I was thinking to myself “Wait, I thought I was going to love this book? Why does everyone else love this book? Am I even reading the same book?”. Turns out I just needed to push my way through the beginning of the book to get to all of the awesomeness! So the beginning is a little slow to start and actually a teeny bit boring honestly but I understand that it was needed to set the stage for all of the cool stuff that happens later.

As I said the beginning is a little slow paced but once it gets going it really gets going! The rest of the story is very fast paced and action packed without any dull moments or lulls. And theΒ  plot twists are BRUTAL by which I mean they’re pretty jaw-dropping, there’s conspiracies, politics, mind games, betrayals, and revenge! How could you ever get bored?

One thing I really thought was interesting was the setting and world building for this story. The galaxy (universe? space in general?) is run by an Imperial Court/Senate type of thing with the ruling figurehead being an Emperor. So this had a very Roman feel to it mixed in with the futuristic/space-y atmosphere. How is that NOT awesome?

I also thought that the world building was just minimal enough to keep you interested and not confused especially since this book was SUPPOSEDLY a standalone when I read it. It was just enough and it was perfect, however, now that this is a trilogy I’m sure they can (and should) expand way more on the world building.


Let’s just say the characters are pretty amazing in this story especially the main character and her love interest I thought the development and complexity was spot on.

Nemesis is our main character and she is a badass, vicious, and ruthless…..I loved her. Her sole purpose in life is to protect Sidonia (who is her charge basically) and she will do this at all costs even if it means sacrificing herself. Her personality is very robotic and animalistic she doesn’t exactly have feelings or experiences like humans, however, she does care for Sidonia and Sidonia cares greatly for her as well and insists Nemesis is human too. Thus we see a lot of conflicting emotions inside Nemesis as she develops throughout the story as she tries to deal with her nature and her growing human feelings. SO MUCH COMPLEXITY, IT IS AMAZING!

Then there’s Tyrus. Holy crap I absolutely loved his character so much, I thought only Nemesis was complex and developed but Tyrus is right up there as well. He’s so clever and when I say clever I mean so unbelievably smart and devious with all of the plot-hatching and mind games. He’s just awesome, okay?

The secondary characters were also pretty great, they had JUST enough development to keep them interesting although overall they paled in comparison to Nemesis and Tyrus. Everyone had their own agendas and additions to the story. Plus the villains are so VICIOUS and cold-hearted that you just loved to hate their guts.


Let me describe this with a gif:

I rarely love YA romances and especially not this much! I adored the romance in this book to little bits and pieces, it had a kind of “forbidden love” feel to it and there were definitely NO tropes or cliches with it either this was a complete slow burn romance. I think that Nemesis and Tyrus fit so well together because they’re both ruthless but also with a strong underlying goodness to them.

Also without naming whos or whats there is a bit of a LGTB romance in here toooooooo!

in conclusion

I very much loved “The Diabolic” it was all kinds of vicious and trope-free and just really unique! There weren’t really a whole lot of things I DIDN’T like about it thus giving it the 5 star rating.

What I Liked:

  • Ruthless, vicious characters
  • A badass main character
  • The romance was so freaking cute and I ship it so hard!
  • The setting and world building were interesting
  • The plot is fast-paced and there’s constant action
  • Space politics and mind games!

What I Didn’t Like:

  • The beginning was hard to get into (the pacing was slow to start)
  • The fact that this went from a standalone to a trilogy even though the ending was perfect for a standalone!


Most definitely I recommend giving “The Diabolic” a read! Especially if you’re into YA sci-fi, vicious/badass characters, and you like a little politics in your plots! Also if you like action because there are things constantly happening!

    I have mixed feelings about it being turned into a trilogy. On the one hand, I felt like the author wrapped things up pretty well and I’m not really sure how she’s going to continue the story. But on the other hand, I really loved this world and I’d love to see more from it. I’ll definitely end up picking up the next book. Time will tell whether or not I’ll actually like it πŸ˜›

      I do as well and I agree 100% with both points you made! I enjoyed it and wouldn’t mind reading more but also I was satisfied completely with the ending so I’m conflicted. Hopefully the next book will be as awesome! πŸ™‚

    Oh, I’m glad you loved this! I didn’t get a chance to read it last year but I’m hoping to soon. Awesome review! I’m glad that I’m finding out now that it’s going to be a trilogy. Maybe when I read it, I can figure out why.

      Thanks Evie! I really hope you love this one when you get around to reading it!
      And it’s definitely good to know going in it’s a trilogy versus a standalone because I was pretty conflicted when I found out after reading. It wraps up 100% pretty much so I’m curious to see how it will end up being a trilogy!
      Can’t wait to hear your thoughts on this book though! πŸ™‚

    Great review of what sounds pretty promising! I have every intention of picking this one up in the future, but when you mention a slow start.. for about what percentage of the book would you say it remains slow? It helps me to know so I do not give up too soon haha πŸ˜‰

      Thank you!
      I would say maybe the first 15% maybe 20% at the most, it isn’t slow for very long but I was expecting all the action a little sooner than it came. So you don’t have to push through for too long, I really hope you enjoy this one! πŸ™‚

        Those are my thoughts as well which is why it’s forgivable they have to start us out somewhere! Hope that encourages you too, haha, it really does pick up right after that! 😊

    I bought this specially because it was a standalone, so I felt very cheated when I found out πŸ˜’ Not even sure whether I still want to start The Diabolic…

      ME TOO! I was so excited to read a YA book that was a standalone because I feel those are kind of rare especially in fantasy and sci-fi!
      However, I’d recommend still reading it because it does have a 100% closed ending with everything wrapped up so even if they are continuing it into a series you can still treat it as a standalone! Which I may or may not end up doing myself. πŸ™‚

      Glad you loved it too! I have mixed feelings on it becoming a series because I loved it and I’d love to visit these characters again but also it was supposed to be a standalone and I thought it wrapped up nicely. πŸ™‚
