The books

  1. Throne of Glass

    Sarah J. Maas · Throne of Glass #1 · complete series

    Spice 1/5 Darkness 2/5

    An assassin dragged out of a salt mine to compete for the king's favor. Book one reads young. Stick with it, because by book four it's a full-blown fae war epic.

  2. A Broken Blade

    Melissa Blair · The Halfling Saga #1 · complete series

    Spice 2/5 Darkness 3/5

    Keera is the King's Blade, a half-fae spy who drinks to forget what she's done for a human king. Hunting a rebel called the Shadow drags her back toward the fae lands she abandoned. Indigenous-inspired and slower than the hype. Readers rate the first two books highest.

    V.E. Schwab · Shades of Magic #1 · complete series

    Spice 0/5 Darkness 2/5

    Four Londons, one magician who can travel between them and a thief who wants to be a pirate. Lighter than most on this list but White London is properly nasty.

  4. A Shadow in the Ember

    Jennifer L. Armentrout · Flesh and Fire #1 · complete series

    Spice 4/5 Darkness 3/5

    Sera was raised to seduce and kill the Primal of Death, who was promised her as a bride and then never came to collect. When Nyktos finally shows up, the plan gets messy fast. Long and repetitive in the middle, and a prequel world for Blood and Ash readers.

  5. Gardens of the Moon

    Steven Erikson · Malazan Book of the Fallen #1 · complete series

    Spice 1/5 Darkness 4/5

    Erikson drops you into the middle of an empire's war with zero explanation and expects you to swim. Sorcerers level cities, gods meddle in Darujhistan's politics, and the Bridgeburners just want to survive. Book one is the roughest. It gets much better.

  6. Grave Mercy

    Robin LaFevers · His Fair Assassin #1 · complete series

    Spice 1/5 Darkness 3/5

    Ismae escapes a brutal marriage into a convent whose nuns serve the god of death, mostly with poison and knives. Then she's sent to the Breton court posing as Duval's mistress. More politics than stabbing, and the slow trust between them really works.

  7. Lady of Darkness

    Melissa K. Roehrich · Lady of Darkness #1

    Spice 3/5 Darkness 4/5

    Scarlett Monrhoe and her sisters were raised to torture and kill on command, and she is very good at it. Book one is long and stingy with the romance. Readers who push on say the later books are where it catches fire, in every sense.

  8. Lament

    Maggie Stiefvater · Books of Faerie #1 · complete series

    Spice 0/5 Darkness 2/5

    Deirdre, a shy harpist, plays the competition of her life alongside a gorgeous flute player named Luke, who happens to be an assassin sent by the Faerie Queen to kill her. Early Stiefvater, a bit rough, steeped in Irish folk music.

  9. Nevernight

    Jay Kristoff · The Nevernight Chronicle #1 · complete series

    Spice 3/5 Darkness 5/5

    Mia watched her father hang, so she enrolls at the Red Church, a school for assassins where failing usually means dying. The narrator talks to you in snarky footnotes, which people either adore or hate. Bloody, horny and very sure of itself.

  10. Poison Study

    Maria V. Snyder · Study #1 · complete series

    Spice 1/5 Darkness 3/5

    Yelena is a day from the noose when she's offered a job as the Commander's food taster. Valek, the chief of security, poisons her so she can't run. An old-school slow burn from 2005 and still one of the better captor romances out there.

    Mark Lawrence · Book of the Ancestor #1 · complete series

    Spice 0/5 Darkness 4/5

    Nona is eight, about to be hanged, and gets rescued by a convent that trains nuns to kill. Murder nuns, friendship and some very nasty politics. Gentler than Prince of Thorns but still Lawrence, so nobody is safe.

  12. The Bridge Kingdom

    Danielle L. Jensen · The Bridge Kingdom #1

    Spice 3/5 Darkness 2/5

    Raised to be a spy, married off to the enemy king she's supposed to destroy. Tight and fast. Great if you like your heroine competent and in over her head.

  13. The Court of Broken Knives

    Anna Smith Spark · Empires of Dust #1 · complete series

    Spice 2/5 Darkness 5/5

    A band of mercenaries is hired to assassinate the emperor of a rotting empire, and one of them, Marith, turns out to be something much worse. The prose is fevered and fragmented, close to poetry. You either love the style or you can't get through it.

  14. The Kiss of Deception

    Mary E. Pearson · The Remnant Chronicles #1 · complete series

    Spice 0/5 Darkness 2/5

    Princess Lia bolts from her arranged wedding to a seaside village, and two new boys turn up: the prince she jilted and the assassin sent to kill her. The book hides which is which for a long time. That trick is the whole fun.

  15. We Ride the Storm

    Devin Madson · The Reborn Empire #1 · complete series

    Spice 2/5 Darkness 4/5

    Three narrators in a crumbling empire: a princess forced to marry for alliance, a soldier from the plains, and an assassin who hears the voices of the dead. The first chapter has a severed head and it sets the tone. Starts confusing, then locks in.
