When Jonah Reed crossed the threshold, he didn’t vanish—he arrived. Beyond the wormhole, an ancient, deliberative presence awaits, a force that has monitored Earth’s progress since its early days. And now, humanity’s decision to refuse alien dominance has drawn its attention.

In Emergence, Earth discovers that autonomy is only the first step. As the anomaly stabilizes and alien empires retreat, something older and far more patient begins interacting with humanity. But it is not interested in domination—it is interested in assessment.

The Variants, once engineered for subjugation, are now stepping forward, as a new kind of humanity begins to take shape. Dr. Elias Vorn struggles to interpret the cosmic signals, while Captain Amara Kincaid faces a world no longer under occupation but instead under observation. And Jonah, now the first human to cross beyond the breach, begins to understand that the universe’s true test has only just begun.

In The Invasion Protocol: Emergence, the stakes grow higher as humanity learns that the breach was not an invasion—it was an invitation.

Because when a species chooses its future…

The universe responds.

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.
