A compelling take on folk horror and macabre rituals, this debut novel uncovers dark secrets about how far people will go to keep their dreams alive. A Goodreads Most Anticipated Horror pick for Spring 2025!

A mysterious stranger shows up at Riccardo’s apartment with some news: his grandmother Perihan has died, and Riccardo has inherited her villa in Milan along with her famed butterfly collection.

The struggling writer is out of options. He’s hoping the change of scenery in Milan will inspire him, and maybe there will be some money to keep him afloat. But Perihan’s house isn’t as opulent as he remembers. The butterflies pinned in their glass cases seem more ominous than artful. Perihan’s group of mysterious old friends is constantly lurking. And there’s something wrong in the greenhouse.

As Riccardo explores the decrepit estate, he stumbles upon Perihan’s diary, which might hold the key to her mysterious death. Or at least give him the inspiration he needs to finish his manuscript.

But he might not survive long enough to write it.
