Review || All Her Ghosts by Cynthia Prith

Published July 7, 2026 by Union Square & Co.

Persephone Green doesn’t have a heartbeat. In a country where the dead has eerily lurked among the living for nearly two decades, even she knows its absence is not normal.

In place of her heart, something inhuman stirs, an ancient ocean she discovers twinned in the chest of Sebastian, the charmingly bizarre new student. When they’re together, they attract ghosts like a beacon, and when they kiss, white flowers bloom in the dead, autumn ground.

To exhume the truth, Persephone and Bas travel across the Midwest to the deserted facility where it all began. Pursued across state lines by writhing swarms of ghosts, militant government agents, and—maybe worst of all—her mother, they unspool a tangled web of conspiracies. At its center: a divine and devastating truth.

Forced to choose between an imperfect life that’s wholly hers or an otherworldly responsibility older than time, the echoes of Persephone's decision will alter the fates of all souls—living and dead—forever.

I've read Cynthia Prith before and really enjoyed A Fairy Hunter's Guide for the Recently (Un)Dead, so I was excited to pick this one up. 

The premise of All Her Ghosts is interesting, especially when Persephone discovers she has no heartbeat. The world-building was probably my favorite part. Ghosts aren't some rare, terrifying thing hiding in the shadows. They're just part of everyday life. People have figured out how to live with them, work around them, and use salt and iron to repel them. They even have Remnant Safety classes at schools. 

Persephone comes across as a very sulky teenager. There are a lot of questions surrounding her and the world she's living in, and all the adults seem to be gaslighting her, her mom included. When she met Bas, her world brightened. The romance goes quickly from adorable to "I would die for you and also possibly die without you". I'm not a proponent of instalove romance, but there’s something sweet about the idea that these two always meant to find each other, especially when they’re both dealing with something so strange and isolating. 

Once things get rolling, the pacing is very fast. There's no shortage of action, and some genuinely interesting ideas. While I was never bored, I did reach the end wanting a few more explanations. Overall though, I liked All Her Ghosts. The world-building and the idea of ghosts being an everyday part of life were unique, and all the secrets kept me curious. It wasn't a new favorite for me, but I had a good time with it.
