“Koster’s debut novel is a twisting narrative of mystery, history, and science fiction.” – Cassondra Aufenthie, author of The Drift

A “unique approach to time travel. Koster allows us to sneak up on it and BAM! you’re hot in the middle of a story that will not let go until it turns you inside out.” – Amazon Review

The Probability of Time by Tim Koster

While investigating a high-profile murder, Detective Liam Smart uncovers a secret war that’s been manipulating the American Political Landscape since the Revolutionary War. As the evidence of his case begins to build, Liam finds that the longer he pursues the killer, the more he gets dragged into the conflict until he has no choice but to join the fight.

Described as a unique blend of a mystery, crime drama, and science fiction, Tim Koster’s debut novel is a well-paced time travel thriller full of unexpected twists and turns, a budding romance, and an ending that will leave you asking “what’s next?”
