“Unlike anything I’ve ever read.” —V.E. Schwab, #1 New York Times Bestselling Author

The Emperor needs necromancers.

The Ninth Necromancer needs a swordswoman.

Gideon has a sword, some dirty magazines, and no more time for undead nonsense.

Brought up by unfriendly, ossifying nuns, ancient retainers, and countless skeletons, Gideon is ready to abandon a life of servitude and an afterlife as a reanimated corpse. She packs up her sword, her shoes, and her dirty magazines, and prepares to launch her daring escape. But her childhood nemesis won’t set her free without a service.

Harrowhark Nonagesimus, Reverend Daughter of the Ninth House and bone witch extraordinaire, has been summoned into action. The Emperor has invited the heirs to each of his loyal Houses to a deadly trial of wits and skill. If Harrowhark succeeds she will be become an immortal, all-powerful servant of the Resurrection, but no necromancer can ascend without their cavalier. Without Gideon’s sword, Harrow will fail, and the Ninth House will die.

Of course, some things are better left dead.

These absolutely live up to the hype. They are bananas in the best way possible - each one has such a different voice, style, tone, structure, but I adore them all! The first book, Gideon is a brilliant locked-room murder-mystery in space starring the best personality clash I’ve read all year - a jock-warrior-girl who just wants to live a carefree life as a fighter,and a burdened-brooding-ultra-serious last-of-her-line necromancer - and it WORKS. It’s enemies-to-lovers, sort of, except not really? I know I sound glib about this one, but the absolute aching beauty of their relationship when they become close is brilliant. And then the second book, Harrow, goes right from the shocking end of book one into an almost stream-of-consciousness, unreliable-narrator ride where neither the protagonist nor the reader know quite what is happening (very purposefully) and the paranoia is justified… it couldn’t be more different of a tone, but it’s amazing. And then Nona, the third book, is utterly different than either of the previous two, starring a cheerful teen who goes about life blissfully not-quite-aware that she is pretty much in the middle of an apocalypse-dystopia… and you just fall in love with her immediately. These books could not be more different, but they are all just SO GOOD.

Gruesome and funny and intense. I think Tamsyn Muir is smarter than I am because I feel as though I lost the plot a few times, but I enjoyed their narrative voice as it grabbed me by the wrist and tugged me through the vortex after it. Hoping very much for a 4th book!

An absolutely mind-blowing space opera that took me on the wildest ride of my life!

What starts as a locked-room mystery in a creepy Space Mansion mid-necromancy contest builds steadily outward until you look up and the whole universe is at stake. Not only a masterclass in unreliable narration, this series is also a perfect balance of scale: sweeping grandeur in one breath and individual piercing heartbreak in the next.

From murder mysteries to secret court politics, from long-running rebellions to an unrequited-requited-unrequited romantic mess, from 'your mum' jokes to a reference to that weird 'S' we all drew as kids, this book has everything. I cannot recommend it highly enough!

This may be one of my favorite series ever. It is ridiculous, complicated, touching, and irreverent. And the audiobook version read by Moria Quirk is easily one of the very best narrations I have ever had the pleasure to listen to.

Genuinely the best book series I have ever read. Cannot recommend enough. It's genre bending, insane, witty, deeply queer, and a fun read. You will be confused at first reading it, but that's all apart of the fun.

I adore this series. It's definitely one of my current favourite series right now. I don't think I enjoyed a trilogy of books so much in a long time.

DNF - I just can’t do this anymore! I’m so confused and the complete befuddlement has led to boredom and I cannot keep going with this any longer. I really really wish I liked it 😭
