About the book

When a librarian discovers an unmarked mahogany door within the depths of the Boston Public Library, she gains access to a clandestine subterranean archive housing manuscripts that function as physical gateways. These volumes contain entire realities where historical events followed different trajectories. As the protagonist learns to navigate these shifts in space and time, she realizes that extracting knowledge from these worlds causes the physical structure of the Boston library to deteriorate. She must track a rogue collector who is stealing rare folios, an act that threatens to collapse the boundaries between the primary world and the fragile dimensions stored on the shelves.

Readers of historical fantasy and speculative fiction will find a detailed look at the tension between preserving information and the ethics of intervention. Those interested in the intersection of architectural history and archival science will see how institutional secrets shape public legacy. The narrative provides a framework for understanding the weight of historical choices and the risks inherent in seeking forgotten truths. By the final chapter, the reader understands the internal mechanisms of a magical system rooted in literature and the high cost of maintaining a doorway between the possible and the real.

Insights from THE ASTRAL LIBRARY

Every library hides a secret world. This one just happens to be made of starlight and ghosts. It makes our local branches feel like holograms.

Rosie is such a mess when we meet her. It feels so real how she hides in her research because people are harder to read than old letters.

“A library is a place where you can be anyone, so long as you are quiet.”

Finding that hidden room in the college library felt like a physical relief. Sometimes you need a space that belongs only to you and your secrets.

The way the different timelines start to blur is haunting. You realize the women from decades ago were fighting the exact same ghosts we are now.
