Linear Shift, by Paul B. Kohler


Peter Cooper, a widowed father of two whose life is crumbling around him—until a bizarre encounter with a desperate Army general launches him on a risky mission: to go back to 1942 and change a moment in time. The repercussions will almost certainly alter the conclusion of World War II. But will the ripple effects stop there? And what kind of life will Peter return to?

I’m a sucker for time travel stories. When I saw this on NetGalley, I had to read it. Linear Shift marries historical fiction with time travel sci-fi in a paradoxical look at governments, time, and history.

The ultimate ending was woefully predictable, but that didn’t stop me from enjoying the read. Fans of intrigue, war, and conspiracies will enjoy this story. The historical aspect wasn’t as detailed as say a book by Harry Turtledove, but sometimes Turtledove lays it on pretty thick. There is enough history to give the story context, but not enough to bog the reader down.

I did find the villainous organization policing the timeline to be clichéd, as was the General that recruited the protagonist. The story did have a long beginning that at times had me wondering where the action was, but the investment in part one pays off in the rest of the book.

When deciding what star rating to give this, I couldn’t decide between four or five stars. As individual books, each part was easy to rate: 3 stars for part one, 4 stars for parts 2 and 3, and 5 stars for part 4. Since I don’t give fractional star ratings, so I’m going to be generous and award five stars. Read Linear Shift – Part one is free on Amazon, but the omnibus is the best value, and all four parts are free for Kindle Unlimited subscribers.


Paul began writing in 1998, shortly after the birth of his daughter. His first short story, Amy, was written in November of that year, but went unpublished until November of 2013. That was when Paul found the courage to publish. Despite the 15 year lag, Paul has written many unpublished works throughout the years. Linear Shift, Part 1 (September/2013) was his first published story, and was the kick off to his four part serial novel. Part 2 followed up in December of 2013, and Part 3 is planned for a May/2014 release. Aside from his Linear Shift series, a number of Paul’s short stories have been included in anthologies. Amy, was included in “Something To Read On The Ride”. Lookout Mountain and Gold Rush were both included in “Something For The Journey”. His short story Alone has been submitted to another anthology, but has yet to be published. When not writing, Paul is hard at work in the field of architecture. He has been in the field of design since 1992, and loves what he does. He lives with his wife and daughter in Littleton, Colorado, where he was born and raised.
