Have you ever been forced to choose between the broken life handed down to you and the thrill of the infinite unknown?
For cousins Zane and Flynn Harper, that choice comes far too soon.

Shaped by tragedy and a future of grim prospects, they never imagined they'd be thrust into the role of galactic protectors. One moment they're ordinary teens—the next, they're navigating dazzling new worlds, impossible dangers, and a galaxy gripped by an all-too-familiar plague of emotional and psychological unrest.

As enemies close in and their core beliefs are tested, Zane and Flynn must learn what it takes not just to survive, but to lead others through the darkest of trials.

Into the Infinite Unknown launches The Cousins Intrepid, a sweeping sci-fi adventure with the wit of The Hitchhiker's Guide to the Galaxy, the imagination of The Phantom Tollbooth, and the wonder and emotional depth of The NeverEnding Story—a tale where the greatest discoveries aren't just across the stars, but within ourselves.

Step aboard the Brava Sentalla and begin the journey into the infinite unknown.
