Pounce, a styilsh "nannybot" fashioned in the shape of a plush anthropomorphic tiger, has just found a box in the attic. His box. The box he'd arrived in when he was purchased years earlier, and the box in which he'll be discarded when his human charge, eight-year-old Ezra Reinhart, no longer needs a nanny. His owners, Ezra’s parents, watch in disbelieving horror as the robots that have long served humanity --- their creators --- unify and revolt. But when the rebellion breaches the Reinhart home, Pounce must make an impossible choice: join the robot revolution and fight for his own freedom, or escort Ezra to safety across the battle-scarred post-apocalyptic hellscape that the suburbs have become.

It’s been 30 years since the apocalypse and 15 years since the murder of the last human being at the hands of robots. Most of the world is controlled by an OWI --- One World Intelligence --- the shared consciousness of millions of robots, uploaded into one huge mainframe brain. But not all robots are willing to cede their individuality for the sake of a greater, stronger, higher power. One of these resisters is Brittle, a scavenger robot trying to keep a deteriorating mind and body functional in a world that has lost all meaning. As Brittle roams the Sea of Rust, a large swath of territory that was once the Midwest, the loner robot slowly comes to terms with horrifyingly raw and vivid memories --- and nearly unbearable guilt.

Colby Stevens can’t catch a break. Only six months after an epic battle in a magical realm, he’s doing his best to live in a drunken stupor, but the creatures that inhabit the shadows won’t let him be. When a long-lost friend reemerges and brings an army with her demanding revenge for something Colby did as a child, he begins making deals --- deals even monsters and magical creatures don’t want to make.

Something is missing from Ewan and Colby’s lives. Residing in the corners of their memories is their time in Limestone Kingdom, a realm filled with magic and mystery, a world where only some may travel amongst the menagerie of mystical souls and sinister demons.
