Nona the Ninth: The Grand Finale to The Locked Tomb Series

Harrow the Ninth

  • Save

Her city is under siege.

The zombies are coming back.

And all Nona wants is a birthday party.

In many ways, Nona is like other people. She lives with her family, has a job at her local school, and loves walks on the beach and meeting new dogs. But Nona’s not like other people. Six months ago she woke up in a stranger’s body, and she’s afraid she might have to give it back.

The whole city is falling to pieces. A monstrous blue sphere hangs on the horizon, ready to tear the planet apart. Blood of Eden forces have surrounded the last Cohort facility and wait for the Emperor Undying to come calling. Their leaders want Nona to be the weapon that will save them from the Nine Houses. Nona would prefer to live an ordinary life with the people she loves, with Pyrrha and Camilla and Palamedes, but she also knows that nothing lasts forever.

And each night, Nona dreams of a woman with a skull-painted face…

Our Review

Despite the Locked Tomb series’ intricate perspectival shifts and complex plot details, the central star-crossed romance between Gideon Nav and Harrowhark Nonagesimus remains its emotional core. In the second book, Gideon’s repeated death and the emergence of a mysterious girl signaled Tamsyn Muir’s commitment to defying conventional narrative resolutions. The lingering question of “Who is Nona?” has intrigued readers since the announcement of the third installment, yet Muir deliberately leaves this inquiry partially unanswered in Nona the Ninth. Instead, she dismantles the elaborate world crafted in the previous two books, grounding her readers in a narrative that feels closer to reality.

Except for some dreams of a woman clad in a painted face, Nona knows nothing beyond her unremarkable life in a city verging on social collapse. Living amongst interplanetary refugees and menaced by a blue sphere in the sky. After Gideon’s street-smarts and Harrow the Ninth’s disorienting use of second person, Nona carries her own unique voice. A little naive and fierce is a brilliant reflection of her age. Moreover, her unwavering love for the world.

After Cam, Pal, and Pyrrha’s efforts to prevent their hopes of finding Harrow and Gideon shape who Nona becomes, it’s difficult to watch the weight of the baroque plot that ostensibly produced Nona suddenly falling on her shoulders, demanding she act accordingly.

Alecto the Ninth is poised for a significant undertaking, and I am confident that Muir will once again astonish us—not just with the tale she unfolds but with her narrative approach. Nevertheless, concluding Nona the Ninth left me with a sense of uncertainty. The fleeting acquaintance with Nona, however inevitable, prompts contemplation on whether the gains justify the losses. In a series unafraid of delving into the darkest realms of death and grief, I yearn to hold onto a character’s assurance that “you can’t take love away.” In a universe where resurrection is possible, the past tense may not be as robust or straightforward as it appears. The Locked Tomb saga unfolds, and the awaited character finally speaks, yet unlike Muir’s characters racing ahead with witty remarks, I find myself still mourning the departed.
