Book Description

The number one best selling high tech science fiction novel in the Kindle store. An Amazon best seller for over a year.

Humanity began as primitive lungfishes, crawling out from the depths of the sea to escape predators. Humanity will end as sparkles of light, streaming across the empty voids of the universe searching for meaning.

Pinhole is about the time travelers who live between what we once were and might someday become.

Cassandra knows the future brings her doom but is helpless to stop it. Lionel executes murderers before they can kill but wonders who the real victims are. Dolores is ensnared in a cult that uses a machine to link their minds and bodies. Joseph strives to escape an eight-year loop he's been trapped in his whole life. Daphne searches for a murderer who kills by giving his victims cancer, but she may be the next target.

Moving through time and space, their lives are intertwined, unwittingly tethered together by the same technology they use to change the world.

About the Author

Matthew Kagle was the youngest of six children born to cattle ranchers in Emblem, Wyoming. He graduated elementary school two years early and went on to study high energy physics at Carnegie Mellon University. He was expelled after an experiment he was running caused university’s linear accelerator to detonate. He quit physics to explore his love of the sea, eventually becoming captain of the Grandcamp (a cargo frigate) which capsized after an unexplained blast in the hold. When his lifeboat arrived in the San Francisco Bay Area, he decided to stay, working at Vacuum Genesis, a video game company ( The first game he designed was recalled from the market due to a programming fault that caused hard drives to accelerate until they broke into high-velocity shrapnel. He moved on to teaching, working at several small colleges and universities, but quit when some of his students spontaneously combusted upon entering the workforce. This is his first published novel. Handle it carefully. You can follow Matthew’s blog at His Twitter account is @makagle.

5.0 out of 5 stars In case Primer was too easy... April 11, 2013
Format:Kindle Edition|Verified Purchase
Loved it. As recreational reading, hits that perfect sweet spot of, "Great fun to read" in the small, and "Oh... I begin to see, no wait" in the large. Which is perfect for my "read half a chapter a night and pass out" lifestyle. I think I need to read it again to enjoy connecting the dots a bit.

It's a series of connected vignettes -- not entirely unlike David Brin's recent Existence -- that eventually weave together into a broader whole. Wonderful and absurd characters and ideas are tossed in throughout. And there's a bit just about half way through involving a conversation at a roadside diner which is Twilight Zone perfect.

5.0 out of 5 stars A rich look at time travel March 20, 2013
Format:Kindle Edition|Verified Purchase
Time travel: yeah, you've read them all. Connecticut Yankee in King Arthur's Court, being trapped in time loops, trying to change the past and failing, using knowledge of the future to change the present, and so on and so on. Have you ever found all the tropes beautifully braided together in a story of all too human inventors who release phase upon phase of their technological discoveries and some of the lives they touch? You have now. Pinhole's rich vignettes introduce us to character after character, some whose full stories we eventually untangle from the knots of time travel and some whose stories unfold in one chapter.

5.0 out of 5 stars Great read! April 5, 2013
Format:Kindle Edition
Multidimensional characters, a fast-paced, gripping plot filled with interesting what-ifs--an altogether enjoyable read! I was especially intrigued by the idea of writing a time-travel novel chronologically, which has many interesting implications for both the plot and the characters!

3.0 out of 5 stars Hmmmm July 16, 2013
Format:Kindle Edition|Verified Purchase
I like time travel stories, but this was a collage of different stories and time travel theories. In addition, the author made a point to lightly add current issues into his book. I felt this story took on the dark nature of man more than his good side. He did link all the stories together, but discontinuously. One story interestingly parenthesized the whole work. All in all, I would say to myself (if I could time travel), don't read the book.
The author does write well, very well; but he needs to develop his stories better and leave the social issues out unless it pertains to the story.

Pinhole is a science fiction novel about time travel, composed of 22 interconnected short stories. Each of the short stories vary in flavor story type and pacing. One story will be an action packed Adventure, Another will be a murder mystery and another will be a thought piece. The effect is a little like looking at a mosaic.

I found some of the short stories where more enjoyable than others with the effect being an interesting somewhat thought pervoking action filled tail. On the down side, it's hard to keep track of all the characters and events. And a couple of the stories fell flat for me. I very much enjoyed Pinhole and look forward to Kagel's next book.

Format:Kindle Edition|Verified Purchase
I've always enjoyed time travel books. Lost count of how many I've read. But I can honestly say that this is easily in the top 2 or 3. I lived all the twists and the flow of the book. This will be one of those books I read again and again just for the pure enjoyment of it!!

I like this story, but it is easy to get confused. Well worth the read, even if you have to backtrack a couple of times. Very convoluted, but very interesting.

Always moving, well auctioned book.
As with most time travel stories it is a "woven fabric".
Well done.
