Preface: Twelve Jackals By Moud Adel presents a great world, with an amazing magic system and lovely characters. Despite its short length, it has succeeded in presenting a new world, one of the greatest magic systems I have seen, and structure an entire story from start to end, giving a satisfying conclusion while giving a clear view to where the main series starts.
Introduction: War Remnants By Moud Adel is the prologue novella for the Forbidden series. It is around 150 pages (which to my calculations should be around... 40-k words). It is a self-contained story that works as an introduction to the world of Mastoperia.
In there, there are four main factions, as well as the overseeing Forbidden warriors. Each faction has their own traditions, features and even completely different magic systems, but it was well done and enjoyable, despite a bit jarring at first when some of those changes (especially technologically) were shown, but it is a non-issue mostly.
Conflict is grown from the very beginning, as the story starts very quickly, and doesn't let you go until it finally ends, giving you the conclusion.
Some point that I saw people have conflict in was editing and proofreading, I was fortunate to not see any of those issues, I did notice one case where a punctuation mark was missing, but that is not a critical issue and did not affect my enjoyment to the slightest.
I have really loved the characters presented here, felt they acted very realistically, and I fell in love with quite a few of them. I would say a few characters were the shining feature of the novel.
The writing style is fast-paced and imaginative, some might not enjoy it, while others will love it. I personally fall into the 2nd category.
I highly recommend reading this book, it has been an amazing read of mine, and I can't wait to go through the rest of the author's books.
Conclusion: If you enjoy fantasy, intricate magic systems, fun battles, and a really engaging story, I highly recommend reading this book.
