Dr. James Carter has spent his entire life chasing answers—answers that lie at the edge of science and imagination. When his experiments unlock the door to a parallel universe, he believes he’s made the greatest discovery in human history. But what begins as a triumph quickly descends into a nightmare.

The world on the other side of the portal is both familiar and foreign—a mirror of his own reality, twisted in subtle yet terrifying ways. As Carter explores this alternate Earth, he uncovers disturbing truths: the boundaries between worlds are thinner than anyone imagined, and something—or someone—is watching from the other side.

When Carter encounters a version of himself living in the parallel world, he realizes that the multiverse is not just a scientific curiosity—it’s a battlefield. With each step he takes, he draws closer to a hidden force that manipulates reality itself. But the more he learns, the more he realizes that knowledge comes at a cost.

As the lines between worlds blur, Carter must race against time to find a way back to his own reality—before the doors between universes close forever.

Parallel Universe is a mind-bending journey into the unknown, blending scientific speculation with heart-pounding suspense. Perfect for fans of Blake Crouch and Michael Crichton, this gripping thriller explores the fragile boundaries of identity, power, and the infinite possibilities that lie within every choice we make.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
