What if your dreams weren't just dreams—but another reality fighting to break through? Grady "Gray" Ledger is a sleepwalker haunted by vivid dreams of an untamed wilderness filled with massive reptilian beasts. But when he wakes one night with a jagged, taloned nail embedded in his abdomen, there is no question his nighttime wanderings are more than just an unconscious habit—they're a perilous journey into another world.
Brane Theory suggests that our reality is just one of many—a vast multiverse where dimensions are layered one upon the next. In his sleep, Gray slips through to Wild-Side, a lush utopia home to the enigmatic, ageless Seeley and their advanced, exotic technology. But paradise is under siege. A ruthless, nightmarish species known as the Elend has begun invading from another Brane, bringing chaos and death to a defenseless and peaceful world.
As Gray's two lives spiral into chaos, he must fight on both sides of the veil between worlds—by day evading the FBI and corporate adversaries, by night waging war against the Elend. With the aid of Esker, a sarcastic Artificial Intelligence guiding him in the waking world, and a ragtag team of Wild-Side's greatest minds, Gray battles to protect his friends and his reality.
