She stowed away for adventure. She stayed to become legend.

Jack Caddigan never expected his stowaway cat Princess to change the course of space travel. But when a feline chase across the starship's controls unexpectedly tears the Amiira Yasmine from hyperspace, something extraordinary happens. Something that shouldn't be possible.

When playful cats accidentally unlock a new way to navigate hyperspace, the crew of the Amiira Yasmine thinks they've struck gold. But someone wants what the Amiira has discovered. Someone willing to do anything to get it.

Meanwhile, a Bythian Navy cruiser is dying in the void, its life support failing after a pirate attack. The Amiira's accidental discovery might be the only way to reach them in time—but no one truly understands what the cats unleashed.

Now Princess must venture where no cat has gone before: into the twisted wreckage of a battleship, where air is running out and time is the enemy. Their only hope depends on someone small. Someone fearless. Someone who's been sneaking through ventilation shafts since day one.

Will the galaxy's first starship cat become its greatest hero—or has her luck finally run out?
