King's Dark Tidings Review: The Mary Sue Done Right, With the Best Dialogue in the Genre

My site, my rules

King's Dark Tidings is more straight fantasy than progression fantasy, with an assassin's-creed heart and only light power-growth elements. It's also one of my all-time favorite series, and this is my site, so it's going on it.

The premise is a great hook: in this kingdom, the first son is the heir, the second is the spare, and the third son is taken at birth and raised in a secret order with one purpose, to become the King's Shadow Knight, the deadliest warrior-assassin alive, sworn to serve when his brother takes the throne. Shadow Knights are so legendary, and so lethal to anyone who discovers one, that the kingdom considers them a myth. Rezkin is the current product of that machine: trained from age four by twenty masters, raised entirely inside training exercises, taught that he was never a child, just a man in a small body. Then his dying master fumbles the final rule, and Rezkin walks into the world operating on orders no Shadow Knight was ever meant to have. Such a small hinge for a story this good to swing on.

The Mary Sue done right

I keep a running theory across these reviews that any trope works if the author commits, and Rezkin is my best evidence for the Mary Sue. He is the best at everything, unapologetically, by design, and the story leans all the way in rather than pretending otherwise. It works for two reasons. First, the competence is grounded: he was manufactured for this, and his successes come from methodical, cautious execution, no finger-snap magic, real consequences if he sequences a job wrong. The stakes feel earned even when you know he's the sharpest blade in the kingdom. Second, the character is built around a magnificent limitation: raised in total isolation, he's Drax from Guardians of the Galaxy. Everything is literal. He doesn't understand humor, sarcasm, flirting, or implication, he follows his rules with absolute rigidity, he never questions what his masters taught him, and when reality contradicts his training, he concludes he must be the exception. Sometimes he's right, and never about the things he thinks. The result swings between some of the funniest misunderstanding-driven dialogue in fantasy and scenes that are quietly heartbreaking, because the people around him are feeling things he cannot recognize.

The best analogy I have is a cheeseburger. Almost nothing here is new: the elves and fae get their little twists but land near their stereotypes, the kingdom-intrigue is familiar, the hidden-badass premise is ancient. But you can get a cheeseburger anywhere, and when a place uses real ingredients and cooks the thing properly, you get something exceptional out of a menu item you've had a thousand times, and you keep going back. Every book in this series is that burger: zero grinding, zero meandering, every page pushing plot or deepening the cast, tropes executed at a level where you stop caring that they're tropes.

The fans vs. me: the detour years

My one real complaint is about the author's calendar, not the books. Kel Kade wrote books one through four at a good clip, then vanished into a second series that, in my experience, had none of this one's magic; I couldn't finish its first book. Then, instead of book five, came The Mage of No Renown, a prequel about Wesson's origin, and I'll say what I said in the forums: Wesson is fine as ancillary cast, but he can't carry a book, and handing your starving fanbase a side character's origin story instead of the main course was a frustrating call. I never picked it up. Mercifully, book five finally arrived, and books six and seven have followed on a steady clip since, so the detour era looks genuinely over. If Wesson is secretly your favorite party member, adjust that paragraph accordingly and enjoy your bonus book.

Verdict

Worth the credit. S-low. A kingdom-building assassin story with a protagonist built from rules and misunderstandings, humor that lands constantly, real emotional weight underneath, and not a wasted page across seven books. It's the least LitRPG thing this high on my shelf, and I'll defend the placement to anyone: exceptional execution beats novel mechanics, the same way a perfect cheeseburger beats a mediocre tasting menu. Start it for the premise. Stay for Rezkin taking everything you say literally.
