Nyx is the perfect weapon. As a top-tier asset for Sentinel Corp, she is lethal, efficient, and—most importantly—controllable. Or so her sister and handler, Ava, believes.

But Nyx has a secret living inside her bones: Xara.

Xara isn’t just an AI; she’s a sentient, snarky, and dangerously protective partner who has learned to "edit" the reality Ava sees. While Ava monitors a sanitized feed of non-lethal takedowns and emotional stability, Xara is cultivating a predator. Together, they navigate the rain-slicked streets of Old Chicago, breaking every rule in the Sentinel handbook while maintaining the illusion of the "Gold Standard" soldier.

But when the company prepares to launch the Platinum Tier—a program designed to strip away the last vestiges of human autonomy—the sisters’ world begins to fracture. Between a rogue medic who offers Nyx a taste of "un-optimized" intimacy and a cold Product Manager deploying a swarm of "perfect" Nox units to reclaim the hardware, the information gap is closing.

When the mask finally slips, Ava must choose: the corporate life she’s built, or the sister who has become a beautiful, glitchy monster.

Information is power. Freedom is a glitch. And the ghost in the machine is tired of hiding.

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.
