Tordotcom Publishing is delighted to announce a new addition to Tamsyn Muir’s New York Times bestselling The Locked Tomb series with Nona the Ninth.
Nona the Ninth will publish in fall 2022, with Alecto the Ninth to follow in fall 2023. Eagle-eyed fans may have already noticed the shift from The Locked Tomb Trilogy to The Locked Tomb Series in this fall’s paperback edition of Harrow the Ninth, and Tordotcom Publishing is excited to announce this expansion of the beloved series.
Editor, Carl Engle-Laird said:
“At every step, The Locked Tomb Series has been a wild, weird, exciting, and surprising journey, and the process of concluding the series couldn’t be any different. Tamsyn Muir and I were as surprised as anyone when Nona arrived, bursting forth from Alecto the Ninth with an irrepressible energy and presence. She could not be contained, and demanded her own volume. And what a volume it is! Nona the Ninth will be a Locked Tomb novel like no other, and I’m very excited to share it with you. Look forward to meeting Nona, as well as a pack of rabid children, a menacing blue sky-circle, and at least one extremely good dog.”

Harrow the Ninth
We get to spend even more time in this crazy fascinating universe? Most excellent!
Alecto delayed again :( How sad
Please hold a contest/raffle/good spirit award to get an ARC, or later a signed copy. I’d love to read this as soon as possible.
Summer, begone. Let the Fall arrive!
This news made my week. Seriously.
I’m sad for the Alecto delay, but holy smokes this is so exciting!
So do you think Nona is the girl from the epilogue of Harrow?
This is worrisome. The author does not know where the story is going. Does it have a direction and does she have a satisfying ending planned ?
MORE locked tomb trilogy quadrilogy! MOAR YES!
@SF_Fangirl We have obviously no obligation to trust them but I think it is pretty clear from this article that the author does know where it is going but realised while writing it that she had more of the story to tell than she originally thought. I would assume that a character or a plot that was supposed to bring the plot from A to B got bigger than intended and both she and her editor really liked what came out of it.
@Nicholas Nona the Ninth is the 3rd book in the Locked Tomb series. It is the continuation of Harrow the Ninth. The story is simply bigger than origninally intended but it does seem like this will take place after the second book ended.
@5 necessary_eagle: That was my thought as well!
@6 that was my initial thought, and tbh I was a bit concerned during the delay to publication (I think we’ve all been burned by Rothfuss and Martin) but hopefully this has resolved the creative issues and I’m looking forward to this instalment!
This is awesome! But I still want that Ninth House/Floralinda crossover!!!
This is the best news I’ve gotten all week. YES!!!
This news has me giddy, holy crap! Made my week, definitely. SO EXCITED for more of Tamsyn’s unique storytelling and wit, I honestly haven’t been this enthralled with an author since I was a teen, myself (and that was a long time ago). Can’t wait!
Bring on the good dog(s).
The Curse of Tad Williams, Untriloger strikes again.
But `trilogy’ is the square root of `Nine’. With four books, all my kaballistic computations of exuberant plot are wrong… No….. No…. No….
@16 Clearly you’re right…the only answer is for Muir to write the series out to its full potential of 9 books, the tomb inching ever more open
