Mossa has returned to Valdegeld on a missing persons case, for which she’ll once again need Pleiti’s insight. Seventeen students and staff members have disappeared from Valdegeld University—yet no one has noticed. The answers to this case may lie on the moon of Io—Mossa’s home—and the history of Jupiter’s original settlements during humanity’s exodus from Earth. But Pleiti’s faith in her life’s work as a scholar of the past has grown precarious, and this new case threatens to further destabilize her dreams for humanity’s future, as well as her own.

Physicist Philip Moray is having a good day. He’s chipping away at his big work project. The lunch in the cafeteria is at least edible. And he’s looking forward to his end-of-the-day drink and a soak in the hot tub. Then, a strange device turns up in his office. A piece of technology he has never seen before–and shouldn’t even exist. Suddenly, corpses start turning up, eco-activists go on the attack, random people suffer bizarre symptoms. And every time the authorities get a lead, it traces right back to Philip and his colleague, Celia Hunt.

In Daretana’s greatest mansion, a high imperial officer lies dead—killed, to all appearances, when a tree erupted from his body. Even here at the Empire’s borders, where contagions abound and the blood of the leviathans works strange magical changes, it’s a death both terrifying and impossible.

Some stories take more than one lifetime to tell. There are wrongs that echo through the ages, friendships that outpace the claws of death, loves that leave their mark on civilization, and promises that nothing can break. This is one such story.

And in a demon-haunted wood, another act of violence linked them and propelled their souls on a journey throughout the ages.
