Lindsey Duga
Lindsey Duga came to publishing the way a lot of genre writers do, by writing the book she wanted to read and refusing to stop. She wrote her first novel while studying Mass Communication at Louisiana State University, and she has been open about being a writer who chases whatever premise will pull a reader out of the ordinary world fastest. Her published work sits across young adult and middle grade, with a consistent pull toward fantasy, horror-tinged paranormal, and speculative romance. Her books have been published by Entangled Teen, and she has more than ten titles listed under her name.
Her breakout is Kiss of the Royal, published in 2018. The premise is the kind of thing that makes people stop scrolling: in a world at war with dark magic, belief in romantic love is outlawed, and the kiss between a Royal and a Knight is a functional weapon that charges magic for the battlefield. Ivy is a Royal who has spent her life treating kisses as ammunition. Zach is a Knight who believes in love anyway. Watching a heroine who has been trained to treat intimacy as a tactical resource run headfirst into a partner who refuses that framing is a very satisfying setup, and it lands squarely in enemies-to-lovers territory before it earns its way into something warmer.
Her other novels move around the map. Glow of the Fireflies, published in 2019, is a Southern-set paranormal about a girl returning to the woods where her father died and finding a magic she does not remember. Roaring, published in 2020, is a standalone set in the 1920s and pitched by its own publisher as The Great Gatsby meeting This Savage Song. She has also written horror-leaning middle grade including The Haunting, Ghost in the Headlights, and Replacement. What links them is atmosphere. Duga is more interested in mood and dread than in intricate magic systems, and her books tend to be short, propulsive, and easy to finish in an evening.
On heat, set expectations honestly. Duga writes young adult, and her romances stay firmly in the 0 to 1 band on the spice scale used across this site. There is longing, there is tension, there is the occasional charged kiss that carries actual plot weight, and that is the ceiling. If you came to romantasy through Fourth Wing or the more explicit corners of the genre, her books will read as chaste. That is not a flaw, it is a different contract with the reader, and Kiss of the Royal in particular gets remarkable mileage out of making a single kiss matter mechanically.
For a romantasy audience, Duga is worth knowing as a bridge author rather than a headline one. She is useful for readers who want fantasy romance without explicit content, for younger readers moving up from middle grade, and for anyone who wants a palate cleanser between longer adult series. Her books also work well as an entry point for the kind of high-concept premise that BookTok loves, since Kiss of the Royal can be pitched in one sentence and understood immediately. If you are still working out what you actually want from a fantasy romance, our reading quiz is a faster way to find your lane than trial and error.
Where to start: Kiss of the Royal, without much debate. It is her strongest concept and her most widely read book, and it stands alone with no series commitment. If the tone works for you, follow it with Glow of the Fireflies for something quieter and more atmospheric, then Roaring if you want the period setting. Her middle grade horror is a separate track and does not need to be read in any order. There is no reading-order puzzle here, which is part of the appeal.
