S.M. Gaither Books

S.M. Gaither is one of indie romantasy's quiet success stories. She built her readership the unglamorous way, book by book, until the Shadows and Crowns series became big enough that Penguin UK picked it up for hardcover editions. That trajectory, self-published serial to traditional shelf space, has become the genre's defining career path, and Gaither walked it before it was fashionable.

Shadows and Crowns is the place to start and the reason most readers know her name. It runs five books: The Song of the Marked from 2020, A Twist of the Blade and The Call of the Void from 2021, A Crown of the Gods from 2022, and The Queen of the Dawn closing things out in 2023. The story follows a mercenary heroine marked by a mysterious plague and dragged into the collapse of empires, gods, and the man she absolutely should not be falling for. The series' calling cards are luscious worldbuilding, epic battles, and banter that does a lot of heavy lifting. This is enemies-to-lovers built on genuine ideological opposition, not one rude conversation at a ball, and the emotional payoff lands because Gaither makes you wait for it.

Beyond her flagship series, Gaither has range. The Serpents and Kings trilogy, the Flame and Sparrow duology, The Drowning Empire, The Shift Chronicles, and What Blooms From Death round out a catalog that leans epic but keeps romance load-bearing. The through-line is scale. Gaither likes gods, curses, and continent-sized stakes, and she plots long arcs that reward reading a series straight through rather than dipping in.

On heat, she sits in the moderate zone of our spice scale. We rate The Song of the Marked a 1.5, and the series builds heat gradually as the relationship develops, which mirrors the slow-burn structure of the whole thing. If you measure romantasy by open-door scenes per book, Gaither will read as restrained, especially early. If you measure it by tension, she delivers more per chapter than plenty of spicier authors. Readers wanting maximum steam should check our spicy romantasy shelf instead; readers who want the ache before the fire are in the right place.

Honest assessment: book one starts slower than the series deserves, spending real time on mercenary jobs and world setup before the central relationship ignites. Some readers bounce off it and miss the payoff, which by books three and four is legitimately excellent. The prose is clean and quick rather than ornate. If you need every sentence to shimmer, this is not that. It is built for momentum, and binge readers routinely clear all five books in a couple of weeks.

Gaither also deserves credit for how she treats her readers between books. Her series interconnect lightly, with some works sharing a broader universe, so longtime fans pick up echoes and cameos that casual readers can safely ignore. Nothing is homework, but loyalty gets rewarded. That approach, plus her steady release pace, has built one of the more devoted reader bases in indie romantasy, the kind that preorders on trust. The Penguin UK hardcover editions of Shadows and Crowns brought a new wave of readers who assume she is an overnight success, and the best answer to that is her backlist: nearly a decade of consistent, completed series, each one a little sharper than the last. Few authors in the genre have a catalog this deep with this few loose ends.

Start with The Song of the Marked and read in publication order. The series is complete, so there is no cliffhanger risk, and it works beautifully as a next stop after Fourth Wing for readers who want the same addictive quality with a bigger pantheon and a completed shelf. If you like Gaither's voice, Serpents and Kings is the natural second series. For enemies-to-lovers completionists, she is close to an automatic recommendation.
