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...

"You will love Nona, and Nona loves you." --Alix E. Harrow, New York Times bestselling author of The Once and Future Witches

"If you've read the first two books in this trilogy, I don't need to say anything to persuade you to pick up Nona the Ninth. If you don't know Muir's characters and worlds yet, then, my god, I envy you. It's hard to think of anyone more inventive, more audacious--more fun!--who is writing science fiction now." --Kelly Link

"Nona's lovely, simple, and occasionally silly voice works especially well in juxtaposition with the dark, dense backdrop of the series so far, creating a riveting contrast. Readers will be on the edges of their seats." -- Publishers Weekly, starred review

"A thrilling, mind-boggling and surprisingly heartwarming story. It hurtles us through time and space, has scientists with God complexes (literally) and features many bouts of necromancy. Be prepared to find yourself yelling, "What? WHAT?" several times over." --NPR "Books We Love"
