Time Hack: A Near-Future Science Fiction Mystery Novel
The award-winning sequel to Artificial Selection.
What if you could have more hours in the day?
ArkTech’s forty-year anniversary is almost here, but Charlotte Vance has bigger things on her mind. She’s determined to protect her home and her best friend, Ben. That means stopping ArkTech’s curious AI from glitching – once and for all.
When Ben wants to know why a young man is braving a violent storm, Charlotte follows a trail that leads to a strange new technology. It trades in the most valuable currency of time.
But Charlotte soon finds herself in a race against the clock. A missing person case pulls her deeper into the mystery – and towards a chilling possibility…
Could Ben’s time be running out?
A glitching AI, a streetwise investigator, and a conspiracy theorist step into a temporal anomaly… but will this punchline be Ben's last?
Time Hack is fun, gripping, and thought-provoking – a clever and insightful mystery for anyone who’s ever wished they had more time.
What Readers Are Saying…
“This is going to sound like hyperbole, but I assure you it's this is one of my favorite books I've read. Ever.”
“A really fun but still intellectually satisfying sci-fi book about an AI-human best friend relationship and navigating a post climate crisis world.”
“The story is witty and thought-provoking, funny but poignant, with sky-high stakes.”
“An easy read, humorous and gripping. Even if you don't like sci-fi, you would enjoy this book.”
“Loved it. Masterful storytelling and world-building, with profound societal questions. J Michael Straczynski, Terry Pratchett and Margaret Atwood all come to mind.”

Loved it. Can't wait for book 3.
Time Hack by Marianne Pickles
Loved it, though seemed dry at times. This had a satisfying ending but with enough issues left open that I'm looking forward to the third book in the series.

This was another round of this fun Sci-Fi mystery series. It took me awhile to come around to the characters in the first book but now I really enjoy them. :)
