When Dr. Sophia Jenkins discovers a mysterious letter from 1889 in her modern-day archives, she never expects it to transport her back in time.

Now trapped in Victorian London, she must work with the letter's enigmatic author, Dr. William Montgomery, to uncover the secrets of the legendary Library of Lost Souls—a repository of knowledge that exists beyond time itself.

As Sophia and William piece together ancient clues and navigate a growing attraction, they face an impossible choice: return to their separate times or manifest the Library fully, creating an entirely new reality that would forever alter both their worlds. With the winter solstice approaching and temporal anomalies increasing, time itself hangs in the balance.

Some bridges between worlds were never meant to be crossed... unless love proves stronger than destiny.
