Time Wall

In this final standalone tale from the world of One Second Per Second, civilization is in ruins from the unintended consequences of time travel. As societies around the globe collapse and history itself becomes the plaything of the empowered few, Joad Bevan knows that the most terrifying consequences of the strange, new physics are still to come. Yet out of this chaos emerges the hope that he can find the woman he has loved across timelines. Now the cataclysm of time's ending is getting close, but a handful of physicists believe they have found a loophole in the laws of nature that might allow humankind to survive. It's a long shot and time is running out... literally.

"Once again, Unwin has combined startlingly original Sci Fi with a pulse-accelerating thrill ride."
- Rob Grant, co-creator of the Red Dwarf television series

"Unwin is a master in the time travel arena."
- Guy P. Harrison, bestselling author of Damn You, Entropy! and At Least Know This

"If Michael Crichton's 1999 novel Timeline had starred as astringent a lead character as Joad, maybe its 2003 movie adaptation would have been better."
- Kirkus Reviews
