FREE BOOK: The Probability of Time is on Sale

On May 18th, my family was blessed by welcoming a healthy new baby boy into our family.

To celebrate, I wanted to do something special so I’ve made the Amazon Kindle edition of my book 100% FREE until Saturday, May 30th.

The first 24-hours of this sale has already seen more than 20 copies of the book downloaded and it has skyrocketed up the Amazon Best Seller’s list to #4,959 overall and #13 and #56 on the company’s Time Travel Science Fiction and Science Fiction Adventure lists, respectively.

I would love it if, over the next few days, I could give away enough copies to reach #1 in both those subcategories. So, please go download your free copy, tell your friends to get a copy, and, of course, don’t forget to leave a review!

About The Probability of Time

The Arrowhead Killer is dead! After a decade of hunting the city of Grimwick’s most notorious serial killer, Detective Liam Smart finally feels the colossal weight of this case lift from his shoulders. Justice for the killer’s fifteen victims has been served — or so he thought.

When a new victim is discovered, Liam fears the killer may have had an apprentice — or worse, he arrested the wrong man. Determined to bring swift justice, he enlists the help of Loralei, a young, enthusiastic historian who may have knowledge vital to unlocking this new mystery.

But as the case’s evidence begins to build, Liam quickly discovers Loralei isn’t just beautiful and smart, she has a secret. And the longer he pursues the killer, the more he gets dragged into the middle of a secret war that’s responsible for reshaping the American political landscape until he has no choice but to join the fight.

The Probability of Time is the first book in The Historians trilogy: a steamy, action-packed thriller about time travel, alternate history, and American secret societies dating back to the Revolutionary War.
